织纳煤田红梅煤矿瓦斯富集的影响因素浅析

Analysis on the influencing factors of gas enrichment in Hongmei coal mine,Zhina coalfield, Guizhou Province

红梅煤矿可采煤层7层,虽然埋深浅,厚度为薄～中厚,但矿区基本属于沼气带,瓦斯含量普遍较高。基于矿区地质资料和瓦斯化验结果,从煤岩组分、煤变质程度、煤层围岩、煤储层渗透性、断层构造及水文地质条件等因素对织纳煤田织金矿区红梅煤矿瓦斯富集的原因进行了分析。

There are seven coal seams in Hongmei coal mine, Zhina coalfield, Guizhou Province. Although the depth is shallow and the thickness is thin, the mining area is basically a biogas zone and the gas content is generally high. Based on the results of geological data and gas test, the gas enrichment of Hongmei coal mine was analyzed from factors such as composition of coal petrography, degree of coal metamorphism, coal rock, permeability of coal reservoir, fault structure and hydrogeological conditions.
