石泉煤矿瓦斯抽采的可行性研究

The Feasibility Study of Gas Drainage in Shiquan Coal Mine

介绍了石泉煤矿煤层瓦斯的赋存特征,通过分析瓦斯涌出量及其渗透特性,论述了其瓦斯抽采的可行性,设计了工作面瓦斯预抽放的系统,并对其抽放系统的成本、经济及社会效益进行了统计和分析。说明该矿的瓦斯抽放可以保证工作面的安全回采,同时可以有效利用瓦斯能源、保护环境,具有较好的经济效益和社会效益,不仅解决了该矿的瓦斯问题,还可为其他类似矿井的瓦斯抽放提供参考。

Introduces the occurrence characteristics of coal seam gas in Shiquan coal mine,through analyzing gas emission quantity and permeability characteristic,discusses the feasibility of gas extraction,designs the pre-drainage system of working face gas,and carry out statistics and analysis to the cost,economic and social benefits of the drainage system.Illustrates the gas drainage of the mine can ensure safely mining in the working face,meanwhile can effectively use the gas energy,protect the environment,and has good economic and social benefits,not only solves the problem of the mine gas,also can provids the reference for gas drainage of other similar mine.
