摘要
瓦斯是煤矿事故发生的重大隐患之一,煤矿瓦斯的抽采和预防工作是关系到煤矿安全生产的重大生命工程。本文以王庄煤矿某工作面为例,介绍了高抽巷技术和本煤层预抽采孔技术相结合的瓦斯抽采方法,对该方法在工作面中的实际应用进行了设计,并对瓦斯抽采的预期效果进行了评估。研究结果表明,高抽巷技术应用于瓦斯抽采,可以有效的降低工作面瓦斯含量,保证工作面煤炭资源的安全生产。
Gas is one of the major hidden dangers of coal mine accidents.Gas extraction and prevention work of coal mine is a vital life project related to coal mine safety production. In this paper, a coal face of Wangzhuang Coal Mine is taken as an example to introduce the technology of high level suction technology in combination with the pre-pumping hole technology, the practical application of this method in working face is designed and the expected effect of gas drainage is evaluated. The results show that the technology of high level suction can be used in gas drainage, which can effectively reduce the gas content of working face and ensure the safety production of coal resources at the working face.
