10. Adoption of Advanced Mining TechnologyAdoption of developed mining technology and sophisticated mining equipment at the mining sites is the mine-owners outlook. Government departments and organisations are to offer their advice to the mine-owners but the decision to accept the advice rests on the latter. In fact, people involved in the trade for quite sometimes know as to what are the potentials of their mines and up to what extent further investment will be feasible. Adoption of advanced and developed mining technologies and use of sophisticated and costly mining machinery and equipment depends heavily on the quality and quantity of the minerals being mined and is not justifiable in all the cases.
11. Mine Safety(i) Safety against Accidents
Mining in general is a hazardous profession and those who enter in the field are exposed to high degree of risk against health, injuries and even to the life. Coal mining in particular, is yet more risky and calls for adoption of failsafe precautionary and foolproof security measures with no room for carelessness. Negligence may be on the part of the management or the workers, it is the worker who almost always suffers the physical injuries or loss of life.
On an average 50 to 60 fatal accidents take place on different mining sites in Balochistan every year. Study of past 10-year accidents record indicate that these mishaps cause about 56 casualties, 35 serious injuries, and 45 moderate to minor injuries per annum. Major mine accidents are usually caused due to one or more of the following factors:
§ Injury due to slip and fall of workers on uneven surface particularly in dark underground areas.
§ Injury during haulage and transportation of the mining materials.
§ Injury due to improper use of hand tools and machinery.
§ Injury by moving machines and during transportation.
§ Injury by coming in contact with live electric wires.
§ Injury due to fall of the roof and collapse of the face or the sides of the mine workings.
§ Injury due to ignoring the precautionary measures and improper use of explosives.
In the case of coal mines, in addition to the above, serious mine accident may result due to:
§ Accumulation of coal dust and methane in work area may cause explosion.
§ Accumulation of carbon monoxide in work area, which may cause toxaemia.
§ Accumulation of carbon dioxide or lack of oxygen in work area, which may cause suffocation.
§ Fire within and outside the mine.
Proper training of the underground mining staff, intelligent use of safety equipment, careful utilisation of machinery, tools and explosives could have avoided many of the accidents in the past. Adequate ventilation of the mine shaft, adit (horizontal tunnel) and incline, etc., vigilant pre-shift inspection of the mine and strict abidance and adherence to the mine safety regulations would considerably reduce chances of the mishaps.
Precautionary and security measures taken at every mine must be satisfying for and have approval of the miners who are the most vulnerable to health hazard and accidents. The Mine Safety Rules contained in Mine Act 1935 are too old to be able to meet the present-day safety requirement. A well-equipped dispensary of reasonable size with qualified and trained medical and paramedical staff is necessary for every mining centre or for a few closely spaced mining centres. The medical and paramedical staff posted at these dispensaries must be specially trained to handle injury and first-aid cases. As precautionary measure, everyone entering in a mine is made to wear helmet and safety glasses, and in case of coalmine, carry a safety light. The mines, particularly coal mines, must be fitted with automatic gas detectors and the mineshaft, adit and incline, tunnel etc., be well ventilated and frequently checked if the ventilation system is working properly. As the return ventilation airways can be used as an alternate "escape passage" during emergencies, it may be made large enough and always kept clean and illuminated for emergency use. Old and damaged timbering in mines also causes frequent accidents due to collapse of the roof and walls, timbering reinforcement, where necessary must be made and its periodic inspection insured. The Chief Inspectorate of Mines must impose heavy penalties if these security and precautionary arrangements are found below the acceptable limits at any mine.
(ii) Safety against Health Hazard
Apart from mine accidents, which may cause instant injury or death, there are also long-term occupational risk factors posing hazards to the mineworkers' health. Such hazards include:
§ Inhalation of coal dust suspended in the coal mine atmosphere.
§ Inhalation of stone dust suspended in mine atmosphere.
§ Inhalation of minute asbestos fibres in asbestos workings.
§ Handling of poisonous, toxic and chemically reactive minerals and materials.
§ Handling of radio-active minerals and materials.
These hazards can be minimised by:
§ Reducing the dust particles in the air by proper ventilation of the mine.
§ Keeping the mine free of the settled dust particles by physical means.
§ Use of dust mask and breathing filters by the mineworker.
§ Occasional lungs radiography of the mineworkers.
§ Change of subsurface to surface duty of the affected mineworkers.
§ Use of gloves while handling poisonous, toxic and chemically reactive minerals and materials
§ Handling of radio-active minerals and materials may be done using lead shield specially designed for this purpose.
12. Conserving the EnvironmentMining operations, if left unchecked, produce severe environmental degradation. It is, therefore, necessary to make the mine-owners / stock pile holders file a detailed Environment Impact Statement (EIS) under the Environmental Impact Assessment (EIA) of the Environment Ordinance, 1983 at the time of planning the mining / stock piling activities. Involvement of the stakeholders at this stage of planning the mining / stock piling activity, is necessary as they are the ones who would be most affected by these activities. Stakeholders would be required to first examine if the filed EIS is as per the norms of the EIA. Their views and comments in this regards are to be given due consideration before the final approval and go-ahead signal is given to the mine-owners / stock pile holders for their respective activities.
The mineral and hydrocarbon exploration and exploitation activities in the environmentally sensitive areas, like national parks, protected areas and coastal and marine environment are to be conducted yet more carefully. All the possible efforts are to be made to keep the environment in these areas as little disturbed as possible. A hedge of barbed wire with blinded screen is erected around the workings and as little noise made as possible, particularly in national parks and wildlife protected areas. The working shifts are to be so arranged that the noisy part of the working could be done during day hours from sun rise to sunset and during nights as little light be used as possible. Arrangement is made to dispose the mining waste and drill cores and cuttings from the site along with their production and in no circumstances pollution of soil, water and the air be allowed. Use of explosives and dangerous and poisonous chemicals is to be avoided as far as possible. Arrangements are made to clear all sort of wastes from these sites and at the close of project, the site is fully rehabilitated in its original form - the form it was before the start of the workings. In case of working in coastal and marine environments, special arrangements are made to avoid oil spill and contamination of the seawater with chemicals and other toxic materials.
