VENTILATION

Introduction:

The objective of any ventilation system is twofold. First, the primary ventilation must course air

through the main airways to the immediate working area out by the working faces, thus making

fresh air available for face ventilation, and then return the contaminated air through return

(exhaust) airways to the surface. Second, the face ventilation system must be designed to

effectively utilize the available air in the immediate working area to sweep the working face, to

capture and remove dust, and to dilute and carry away gas, if any, emitted during mining

activities. Without a properly designed ventilation system, an efficient production cycle would

not be possible. The system should provide the required air volumes and quality at reasonable

pressure losses, perform with minimum interference and cost to production, and do so in the

most cost-effective way possible.

Furthermore, the primary ventilation system may be well designed, but if the available air

brought to the working area is not properly utilized for ventilating the faces where most workers

are located, the total system has failed (Bossard, et al., 1982).

Ventilation Equipment

The mine is provided with two exhaust type fans i.e. one AF -100 (Axial flow )

installed at surface that provides adequate ventilation in all the working of OC 1&2

mine and other one is A PV-200 (Axial flow ) has been installed as stand- by . Auxiliary

fan (2 no.s) for LHD .Districts are installed to course air within 4.5m at the working

face. There are 2 no.s of intake air way s and one return air ways such as 6th incline

, 7th incline and 10th incline .

MINE WORKING

In Orient Colliery Mine No 1&2, HR Seam-III & HR Seam-IV are being developed by Bord and

Pillar method with deployment of LHD. The mine is a semi-mechanized mine. Possibility for

depillaring is being explored.

Size of pillar: square pillar (30m x 30 m)

Panel size: Variable (approx... 600m x 100 m)

SUPPORT SYSTEM

Working districts are supported by roof-bolts with full column grout as per approved ssr.

The general pattern of support at face is 3 bolts in a row with spacing of 1.2 m between rows

and 1.5 m between bolts in a row. The 1st row of bolt shall be put not more than 1.2 m from the

face. Side bolts shall be inclined towards the sides & center bolts shall be vertical or normal to

bedding plane. Junctions are supported by additional 25 % roof bolts. Roof stitching is also

practiced in addition to roof bolts in bad roof condition and properly lagged with sleepers.

Anchorage testing machines are used for testing 10% of erected roof bolts in each shift.

Anchorage testing is being done at half an hour, 2 hours, 24 hours & 28 days after erection of

bolts. Two anchorage testing machines are provided i.e. one in each working district. The

tested bolts are properly tagged for its identification.

Sufficient roof bolting crew is available to work as substitute in absence of regular crew.

In order to determine the system of support to be followed, Rock Mass Rating (RMR) is

Determined for the immediate roof, say, up to 2 m above gallery height. For this purpose, generally, the

following parameters are considered:

Layer thickness,

Structural features,

Rock weathering ability

Rock strength, and

Ground water seepage.

Details of systematic support rules:-

Support at development workings--- The roof of the development workings, not exceeding 4.2

m in width, within 10 m of the face is supported by 3 full column cement grouted bolts in a row, with

the row spacing not exceeding 1.2m. The bolts in the same row is so installed that their spacing does not

exceed 1.5m, and the maximum distance of the bolts from the pillar side does not exceed 0.60m. The

last row of support shall not exceed 1.5m. Side bolts is fixed at an inclination of 55-60 degrees from the

horizontal.

Support at junctions--- Every junction of the roadway immediately out bye of the development

face, is supported with full column cement grouted bolts in a manner that spacing of such bolts in the

same row does not exceed 1.5m and also row spacing does not exceed 1m to ensure 25% extra support

at junctions.

GENERAL

a) The roof bolts used is of dimension 20-22 mm in diameter and 1.5m in length.

b) The bearing plates used is MS plates of size 15cm*15cm size and 6 mm thick with center hole.

c) Quick setting cement capsules are being used for full column grouting.

d) 3 cement capsules were inserted into each drilled hole and hold in place with the help of roof bolts, rotated

a no. of times, then bearing plate is tightened to its place with the help of the nut & bolt.

e) Support pressure taken up by the roof bolts is 8-10 tons after 24 hours of installation.

ANCHORAGE TESTING:--

1. At least 10% of the bolts installed should be tested for anchorage, by selecting bolts randomly.

2. Of the tested bolts 90% should be tested as follows:

ANTICIPATED IMPACT AND MITIGATION MEASURES:

There will be impacts on air, noise, flora and fauna due to mining and its related activities.

1. Air quality impact & control measures

The air quality of the OC-2 mine w.r.t SPM , NOx , SO2 , etc. concentration levels is found to be within

limits of the prescribed standards at all stations located in core and buffer zones & is being monitored

regularly. Therefore no effects either on human being or flora and fauna is found to be observed as suitable

mitigation measures are taken to make the operation eco-friendly.

The preventive measures in this context is listed below:

In Underground---

Regular cleaning of spillages to prevent dust being airborne.

Water spraying at transfer points.

Regular ventilation survey as per statutory requirement.

Adequate firefighting arrangements in the mine.

Careful removal of loose coal from the abandoned coal face.

Prompt removal of wood cuttings, oil & grease from underground workings.

On the surface---

Black topping of service roads to prevent generation of dust on surface.

Water spraying on all roads to minimize dust generation.

Mechanized coal transport system.

Unmetaled roads are kept from ruts, pot-holes, etc.

Greenbelts around infrastructure sites, mine return & colony sites.

Schedule of water spraying arrangement---

Water spraying by tanker in underground haul road.

Presently the spraying arrangement is carried out weekly, fortnightly & monthly.

In some old working areas, spraying is done quarterly.

In tippler zone and transfer point area, spraying of water is done by surface water tank.

2. Impact assessment on hydrology & hydro-geology and control measures

-On surface water sources

There is no significant drainage traversing the area except over land flow slopes.The major impacts are

water pollution due to oil & grease, contamination of water bodies due to discharge of mine-effluents and

pollution from domestic & sewage effluents. Groundwater aquifers may get disrupted and also due to

continuous pumping out of mine water, the water table of the surrounding area may get lowered resulting

in scarcity of ground water.

Control measures:

(i) Domestic waste water is treated in soak pit and septic tank combination provided to each unit.

(ii) Treatment of mine discharge water before discharging it to surface water course.

(iii) Recycling of treated mine discharge water to achieve zero discharge to the extent possible.

(iv) Provision of oil & grease trap, provision of drains around coal dump / stock yard.

3. Impact assessment on noise quality and control measures.

Impact:

Abnormal and loud noise have auditory effect. But, the ambient noise level of OC-2 mine is being

monitored regularly. Noise levels are within the limits of the prescribed standard.

Control measures:

All vibrating machines are mounted on vibration absorbing pads.

Enclosure of fan, etc. Adoption of personal protective devices to all persons working in high noise areas.

Regular monitoring of noise levels at various points.

4. Impact assessment on blasting vibration and control measures

Impacts:

Safe blasting measures are adopted .So, there will be no effects on life, property and ambient noise.

Control measures:

(i) All provisions of coal mines regulations are followed.

(ii) Using the particular quantity of explosive as decided as per conditions imposed by DGMS.
