封闭式采煤方法的探索

论述中国采煤的历史,中外采煤技术的发展。建设性提出封闭式采煤方法的设计方案及该方法需要解决的问题。2006年我国原煤产量超过20亿t,这意味着有120亿~200亿m3的煤层气被排到大气中,浪费了能源,也污染了环境,此外瓦斯爆炸问题一直是个"顽疾"。采用封闭式采煤方法很好的解决了这几个问题。

Probe Into the Method of Closed Coal Mining

The history of coal mining in China and development of mining technology at home and abroad is discussed in this paper,design plan of method of closed coal mining is proposed in a constructive way,the problems should be solved. The output of raw coal of our country exceeded 2 billion tons in 2006,this means that there is 12 billion～20 billion cubic meters of coalbed methane has been discharged to the atmosphere,environment is heavily polluted,in addition gas explosion is always a big problem,the adoption of the method of closed coal mining will solve the problem which are mentioned above.
