SAFETY POLICY OF COAL INDIA LIMITED

MINE SAFETY

Coal India Ltd has always given the highest priority towards “Safety”. In CIL, safety is considered as a part of its core production process and is embodied in the statement. CIL has also framed a distinct and definite Safety Policy and formed multidisciplinary Internal Safety Organisation(ISO) in every subsidiary company and also at CIL (HQ). Over the years the safety performance in CIL has been significantly improved. This improvement documented statistically in several independent sources and attributed to the following reasons:

• • Commitment by the management, workers and regulators.
• • Well thought out and conscientious safety awareness drives.
• • Advanced and continuous training of the workforce.
• • Technological advances in the field of mining methods and better mining equipment/ machinery design.
• • Strong oversight and required assistance from the Ministry of Coal.

 

OBJECTIVES OF CIL SAFETY

The objective of Coal India Ltd is to achieve “Zero Harm Potential” in all mines and other establishments. Safety is given prime importance in the operations of CIL as embodied in the mission of Coal India Ltd. CIL has formulated a Safety Policy for ensuring safety in mines and implementation of which is closely monitored at several levels.

• 1) Operations and systems will be planned and designed to eliminate or materially reduce mining hazards;
• 2) Implement Statutory Rules and Regulations and strenuous efforts made for achieving superior standards of safety;
• 3) To bring about improvement in working conditions by suitable changes in technology;
• 4) Provide material and monetary resources needed for the smooth and efficient execution of Safety Plans;
• 5) Deploy safety personnel wholly for accident prevention work;
• 6) Organize appropriate forums with employees representatives for Joint consultations on safety matters and secure their motivation and commitment in Safety Management;
• 7) Prepare annual Safety Plan and long term Safety Plan at beginning of every calendar year, unit-wise and for the company, to effect improved safety in operations as per respective geo-mining needs to prepare the units for onset of monsoon, to fulfill implementation of decisions by Committee on Safety in Mines and Safety Conferences and to take measures for overcoming accident proneness as may be reflected through study of accident analysis. Keeping priority in sensitive areas of roof-falls, haulage, explosives, machinery etc.
• 8) Set up a frame for execution of the Safety Policy and plans through the General Managers of Areas, Agents, Managers and other safety personnel of the units.
• 9) Multi-level monitoring of the implementation of the safety Plans through Internal Safety Organisation at the company headquarters and Area Safety Officer at area level;
• 10) All senior executives at all levels of management, will continue to inculcate a safety towards accident prevention of their functioning;
• 11) Institute continuous education, training and retaining all employees with the accent placed on development of safety oriented skills;
• 12) Continue efforts to better the living conditions and help of all employees both in and outside the mines

REPORT OF ENVIRONMENTAL DETAILS OF TIPONG COLLIERY

The Tipong underground mine is the Eastern most coal mine of the Makum Coalfields and it is situated at a distance of 27 km from Margherita. The project area under reference lies between N 27°18¢ 54 ² and E 95°49¢40 ². The area is approachable from Margherita by the NH-38 and NH 153 up to Tirap gate and from thereby 3 km of forest road where the colliery road branches out for a distance of 1.4 km up to the coal loading point.
Mine entry is located 2.5 km from the coal unloading point.
Tree samplings are planted at various sites.The year wise details of tree plantation are given below:
