冷水江煤矿瓦斯抽采利用现状分析与研究

Analysis and study of coal mine gas extraction and utilization in Lengshuijiang

冷水江乡镇煤矿分布在冷江矿区、渣渡矿区、金竹山矿区,矿井设计生产能力小于9万t/a。煤层薄、构造复杂、渗透性差,瓦斯灾害严重又难于抽采。近年来实施安全改造推广瓦斯抽采利用,有效地促进了各煤矿在瓦斯超限值以下开拓、开采,杜绝了较大瓦斯事故的发生。

The coal mines of Lengshuijiang township are located at Lengjiang,Zhadu and Jinzhushan mining area.The mine design capacity is less than 90 000t/a.The gas disaster is severe and the gas is hard to extract because of the thin seam,complex structure and poor permeability.In recent years,the safety measures were adopted and the gas utilization technique was extended,which promoted the mine development and mining under the disallowed gas concentrate,and put an end to gas accidents.
