煤矿井工生产是地下作业,受自然条件影响约束很大,不同的地质构造和煤层的赋存条件决定了必须采取不同的开拓开采方法,并且带来了许多自然灾害,如瓦斯、煤尘爆炸、矿井火灾、顶板冒落、矿井透水等等,这些都是煤炭生产特有的不安全隐患,人们稍有不慎,就可能造成巨大的不幸。而且煤炭生产系统复杂、工
Coal mine production is underground operation, subject to natural conditions, constraints, different geological formations and coal seam conditions determine the need to take a different exploitation and mining methods, and brought many natural disasters, such as gas, coal dust explosion , Mine fires, roof caving, mine permeable water, etc. are all insecure risks peculiar to coal production. People may cause tremendous misfortune if they are not careful. And the coal production system is complex, workers
