RECOMMENDATIONS OF THE NINTH CONFERENCE ON SAFETY IN MINES HELD ON 2ND AND 3RD FEBRUARY 2000, AT NEW DELHI.
1.3 In respect of small-mechanised mines, which are operating in non-coal sector, it may not be feasible for a small organisation to create a special department on Occupational Health Services. For such small mines, it is suggested that an Association of small mines operators creates common facilities and infrastructure for occupational health services. Creation of such facility is specially needed for asbestos, manganese and mica mines.
Simultaneously with creation of facilities for occupational health services, it is also necessary to improve quality of life of employees working in mining industry by provision of well planned housing colonies provided with all modern facilities such as good drinking water, good sanitation, drainage and recreational facility.
1.4.2 Wherever practicable, roof bolting as a method of support in coal mines should be used. Its performance should be monitored regularly. A few conventional timber props may be used as indicator props.
1.4.3 Coal mining companies should take initiative to select/promote development of suitable type of drills & other accessories for use in various types of roof strata. A task force may be created for the purpose which may oversee the introduction of steel supports.
1.4.4 Development of a portable instrument for detecting the hidden slips in the roof of coal mines should be taken up on priority by R&D organisations.
1.6 The recommendations of DGMS (Tech) Circular No.18 of 1975 shall be implemented forthwith.
1.7 Audiometry should be introduced, as a part of mandatory medical examination, for persons seeking employment in mines and for persons engaged in operations/areas where noise level exceeds 90 dB(A).
1.8.1 The portion of surface haul road in mine premises where there is heavy traffic of men and machines, should have a separate lane properly fenced off from the haul road for pedestrians and two wheelers.
1.8.2 Trucks and other heavy vehicles, not belonging to management should not be allowed in the mine premises without a valid pass issued by the competent authority of the mine.
Before the pass is issued the mine engineer should check the road-worthiness of such vehicles.
In order to check entry of unauthorised vehicles in mine premises, each mine should establish properly manned check gate(s) at the entrance(s) where record of entry and exit of each such vehicle should be maintained.
At the check gate the license of the drivers should also be checked for eliminating the possibility of unlicensed persons driving the vehicles.
1.9 Persons engaged in surface operations and, in particular, the contractors' workers, who incidentally are often inexperienced and least informed about job-safety matters, need closer and more competent supervision. To minimise accidents due to surface operations it would be ensured that:
All persons engaged at any work within the mine premises through the contractors have received relevant training and other job-related briefings and that the drivers of vehicles belonging to contractors entering the mine premises have additionally been explained the salient provisions of "traffic rules".
Each mining company should draw up appropriate training schedules and modalities in this regard and implement the same.
In case of smaller mines, such arrangement may be
made by association of mine operators.
2.0 Preventing Mine Disasters from Inundation
2.2 Suitable infrastructure at area level may be provided for drilling advance bore holes to detect presence of waterlogged workings in advance.
2.3 Embankments provided against river and jore to guard against inundation should be designed properly keeping in view the engineering parameters. The details of such construction should be properly shown in the underground plan and water danger plan.
2.4 Surface excavation or disturbance in or near major sources of water, which are connected or are likely to be connected to below ground workings should be filled up completely.
2.5 Detailed precautions against inundation may be laid down while working beneath or in the vicinity of river and major water bodies. This may include framing and implementing standing order for safe withdrawal of persons, including system of information both manual and automatic, effective communication system and system of safe and timely withdrawal of persons to safety.
2.6 Mechanism may be developed for warning mines about impending heavy rains similar to warning of impending cyclone issued in coastal areas for taking necessary action. Also coordination with concerned agencies/departments about opening of dams in the rivers on the upstream side should be examined.
2.7 Winding system serving as sole means of ingress and egress may be made constantly available even in adverse weather conditions, failure of steam or electricity or any other reasons.
2.8 Effective communication may be established within the mine and between mines for safe withdrawal of persons. Necessary standing orders in this regard need to be framed and enforced.
2.9 Recommendations of 6th Conference on Safety in Mines to evolve suitable cadre structure for mine surveyors and upgradation of their skill by availing facilities at various institutions, appointment of qualified surveyors and providing infrastructure including computerised facility at area level to oversee survey work of the mine etc. may be implemented.
2.10 R&D efforts should be continued to develop a system for construction of water-tight chamber as last refuge below ground in case of inundation.
3.0 Preventing Mine Disasters from Fire, and Effective Emergency Response
