Winter 2016 Coal Mine Safety Protection Measures

In order to ensure the safe wintering of mines and ensure the safety production of mines and the healthy life of employees, according to the document spirit and relevant requirements of the local government and the higher authorities on solidifying and coping with the cold freezing weather, combined with the actual situation of our mine, the following coal mine winter safety measures are specially made.

First, the target mission

We will further strengthen safety production, consolidate the achievements in the establishment of safety quality standardization, inspection and control of hidden accidents, and special rectification and inspection of safety activities, implement safety production responsibilities, strengthen supervision and inspection of safety production, counteract three kinds of violations, and prevent winterization, freezing, fire, and slippage in winter. "Anti-gas poisoning," the work mentioned on the agenda, early arrangements, early deployment, early action, and actively take effective measures to eliminate fire accidents, eliminate serious injuries caused by fire and more accidents; safe and rational use of electric ovens, coal stoves Prevent the occurrence of electrical fires and gas poisoning accidents; use industrial salt, sand and water pipes to wrap thermal insulation materials outside the pipeline to ensure the safe operation of vehicles, the smooth flow of water supply pipes, and the absence of roof falling from the wellbore.

Second, organization and leadership

In order to strengthen the leadership of the mine's “cold protection, freezing prevention, fire prevention, anti-skid, and gas poisoning prevention” work in winter, the leading group of the mine safety production team has decided to establish the leading group of “cold protection, freezing prevention, fire prevention, anti-skid, and coal gas poisoning” in winter.
