What is hydropower?

• Hydropower is the use of high pressure water (100 Bar to 250 Bar) to power, drive and operate various items of equipment such as drill rigs, rock drills and hammers, rock loaders, box hole chutes, water cylinders, cooling fans, pumps, emulsion explosive mixers, anfo loaders, grout pumps, chain saws, jetting guns, blast hole desludgers, water intensifiers, mud guns, skip arrestors as well as the control of actuators and pilot systems on the HPE valve range.

• Hydropower is an alternative energy source to compressed air, oil hydraulics, electrical and combustible fuels.

• Due to the efficiency of hydropower it creates opportunities to save on energy, improve on safety, health and the environment as well as an increase in production.

Hydropower impact on safety, health and environment

Hydropower is proving to be a practical and user friendly source of mining and it contributes to an improvement in the safety and health aspect of deep level underground mining of narrow tabular ore bodies.

• An extremely important contribution of hydropower towards safety and health is its potential to reduce hazardous noise in the work place to acceptable levels. This must be considered as a major breakthrough in the hearing conservation programmes currently being applied.

• Exhaust air from pneumatic rock drills contains oil vapours, which are harmful to one’s health. The presence of oil in the stope adds another dimension to the safety and health aspect due to slippery footwall conditions. The oil vapour also causes contamination of the ore bearing rock which could have an adverse effect in the process plant.

• Compared to pneumatic drilling, hydropower drilling has improved visibility due to the absence of dense fog associated with compressed air caused by the condensation of the humid air when brought into contact with the exhaust air from a pneumatic rock drill.

• Due to the high efficiency of the powerful hydropower rock drill over pneumatic and electric drilling, the time spent on the face by the rock drill crew is reduced, which limits the exposure of personnel to extended periods in the high risk zone.

Design Standards and Philosophy

Valves

The HPE valve range covers a broad spectrum of requirements and is mainly used in underground applications

where the valves are exposed to high pressures, arduous conditions in terms of the corrosive environment and

dirty and contaminated water.

Design standards and philosophy

• Rated up to 250 Bar working pressure

• Conform to ANSI B16.34 specifications

• Y-pattern globe type valve body for reduced pressure drop. Angle pattern bodies are also available

• Ability to maintain in line

• Cast steel bodies with the option of being hot dip galvanised

• Stainless steel and bronze internals

• High dirt tolerance

• High cavitation resistance due to poppet, seat and cage design

• Valve actuation done by electric control or through hydropower water with its hydrologic control

Drill Rigs and Mechanisation

HPE identified the huge divide in South African mines between hand held drilling and electro hydraulic operated

drilling machines in terms of safety and power and subsequently set out to satisfy the need for powerful drilling

machines that are low on complexity and intuitively obvious to operate, whilst at the same time also removing

the operator from the danger area.

Hand Held Hydropower Drilling - Closed Loop

Hydropower drilling improves on the health, safety & environment

and has a dramatic improvement on the drilling speed compared to

compressed air & electric drilling. The Drill can be operated with or

without a water return line i.e. water used to power the drill, other

than for flushing, can either be dumped onto the floor

or returned to the power pack via a return line hose.

The return line water can either be piped straight

back into the mine service water supply line or into

a level controlled tank from where it is pumped

through a filtration system back into the Power

Pack suction line.

• Drill steel diameter 22 or 25 mm hex

• Drill water consumption 1 ℓ/sec

• Return water to power pack – closed loop 0,7 ℓ/sec

Pump Control Valve (Electric Control Actuator)

Pump Control Valves protect pumps and pipe lines against any

damage that may result from starting/stopping or flow surging

caused by an electrical trip out. This is achieved by keeping a

back pressure on the pump and by minimizing the pressure

surges (water hammer).

Manual Isolation Valve

To manually isolate flow at a very high pressure but with a low

hand wheel force and also to throttle flow for extended periods

of time.

Surge Relief Valve

The purpose of the Surge Relief Valve is to rapidly open when the

pressure reaches a pre-set limit thereby eliminating excessive

pressure surges or over pressure conditions.

Pump Column Protection

Pump Column Protection is required on every mine dewatering

system to eliminate/minimise the risk of bursting a pipe due to

pressure spikes (water hammer) caused by a high velocity change,

separation cavitation change or uncontrolled pump stop or start.

Pump Control Valve (Hydrologic control actuator)

Pump Control Valves protect pumps and pipe lines against any

damage that may result from starting/stopping or flow surging

caused by an electrical trip out by minimizing the pressure surges

(water hammer) and by keeping a back pressure on the pump.

Surge Anticipation Valve

The purpose of the Surge Anticipation

Valve is to prevent pressure surges

above the steady state pumping

pressure in the event of a pump

tripout, entirely by mechanical means,

thus eliminating the need for electrical

systems that require a battery UPS

back-up.

This system detects a surge before the

actual event happens, which ensures

that the surge will not exceed the

column pump out pressure.

Non Return Valve

To minimize pipeline pulses (water hammer), generated by a

pump trip out, by closing rapidly in the reverse flow direction.

It is mainly used with Pump Control Valves in mine dewatering

applications.

Air Admission Valve

To allow air to be admitted to the pipe and thereby prevent a

vacuum forming in the pipe.

Energy Dissipator

To destroy pressure energy in fluids so that the energy can be

reduced by a finite desired amount.

Excess Flow Control Valve - high pressure

The purpose of a Safety Isolation Valve is to shut off in the event

of an excess flow condition resulting from a pipe burst or in

circumstances where flow rates need to be controlled without

causing a pressure surge (water hammer) in the process. The

trip mode is in 2 stages - initially very rapid to prevent a runaway

flow, then slowly to give a soft shut off. The trip flow is normally

set at 35% above the working flow rate.

Turbine Control Valve

To achieve rapid closure followed by slow shut off on turbine

nozzle pipelines. This minimizes pressure surges (i.e. water

hammer) and prevents pelton wheel turbines from over speeding

in the event of loss of electrical load.

Flow Control Valve

To supply high pressure water for the descaling of rolling

mill products in the steelworks industry. The valve has the

characteristic in that it first fills the descaler manifold before

it fully opens to eliminate water hammer in a partially empty

descaler system which can occur during the waiting period.

The opening and closing are done in 2 stages with both stages

controlled over a certain time to prevent water hammer.

Dam Level Control Valve

The system consists of a Dam Level Control Valve, Pilot System

and Energy Dissipator to control the level of water in underground

dams, to limit flow to specific requirements and to eliminate

noise and cavitation. Controlled opening and closing of the valve

prevent pressure surges.

Pressure Reducing Station

Pressure Reducing Stations typically consist

of one duty and one standby leg. Each leg will

comprise of an Inlet Isolation Valve, Strainer,

Pressure Reducing Valve and Outlet Isolation

Valve. A Surge Relief Valve is installed on the

common downstream line.

Excess Flow Control Valve - low pressure

The purpose of a Safety Isolation Valve is to shut off in the event

of an excess flow condition caused by pipeline failure or excess

consumption from downstream operations without causing a

pressure surge (water hammer) in the process. The valve can be

manually or hydraulically (water pressure signal) closed and then

reopened without an excess flow condition occurring. The trip

flow is normally set at 35% above the working flow rate.

Pressure Regulating Valve

Pressure Regulating Valves accurately maintain a constant

preset downstream pressure, regardless of changing upstream

pressures or flow rates, with controlled response designed to

ensure stability and minimal line surging when flow changes

rapidly downstream.

Pressure Ratio Valves accurately maintain a set differential ratio

between upstream and downstream pressures.

Backfill Diverter Valve

To divert the flow of backfill material from one point of placement

to another and also to divert flushing water away from the

placement point when pipes are flushed at the end of a backfill

placement cycle. Furthermore to ensure that the placed backfill

material is not diluted or washed away by the flushing water.

to control the loading of the rock into hoppers which can be

operated off low pressure mine service water, high pressure

hydropower water or compressed air.

The Box Front System includes the frame & platform as a package.

Major features include a double door system and ease of installation.

Ventilation Fan

To provide an intrinsically safe flow of ventilation air in standard

570 and 762 mm ducts (available in 15 and 22 kW) using

hydropower as the energy source whilst cooling the air with the

turbine outlet water.

Water Jetting Gun

The Water Jetting Gun is a hand held water jet tool

that uses a high pressure water jet to move broken

rock, more particularly in a stoping environment

where rock is moved into the scraper path. Alternatively the gun

can also be used for sweepings in the stopes. A bigger version

- the Cannon - has a high impact force and is used in a stoping

environment to move broken rock down dip into a gully of a 25

to 30 m panel.

Water Jet Pump

To use high pressure water as the energy medium

for the pumping of contaminated water from

sumps, drains or for cleaning dams.

Chainsaw

The air or hydropower Chainsaw allows a single person

to easily and quickly cut timber ‘sticks’ up to 300 mm in

diameter – to the correct length and at a small angle if

desired (used in a stoping environment for permanent

hanging wall support).

Hydro Compressor (Anfo Loader)

The purpose of the Hydro Compressor is to provide sufficient

air pressure and flow to clean and flush holes and to load

explosives into blast holes.

The Hydro Compressor provides compressed air for

either a special anfo loading hopper, an explosive

capsule gun or any other device that requires

compressed air (e.g. grout guns).

Pipe Connector

To offer an alternative to flanges when high pressure pipes are

coupled for working with pressures up to 250 Bar. The advantages

over a flange coupling is cost and time saving when pipes are

coupled. The pipe connectors are suitable for schedule 40 up to

160 pipe. A feature of this connector is that the hubs are identical

i.e. no male or female sides and the seal acts as a spigot when

aligning the pipes.

Furnace Tapping System

The Furnace Tapping System offers low cost, low maintenance

and safe servicing in submerged arc furnaces, specifically for

the ferroalloy production industry. HPE’s Mudgun, Drill and Poker

Systems are driven by an environmentally friendly and fire safe

hydraulic system which is operated on

additive free potable water.

Typically, a complete taphole service

system consists of a clay pump called a

Mudgun for closing of a taphole, a Taphole

Drill which drills the taphole through the

wall, and if desired, a Poker to break

through to start the tapping.
