摘要
本文以新疆小东沟煤矿为例,分析煤田火区熄灭后,地面塌陷承接降水,因煤层中的黄铁矿氧化生成硫酸,使煤层继续氧化,其形成机理、特征、产生条件,对煤田火区的勘探以及治理具有重要的意义。
In this paper, For example Xinjiang Xiaodonggou coal mines, To andyze： When coalfield fire is extinguished the fire zone like a catchment since ground subsidence there for collecting the precipitation. Therefore, the pyrite embedded in the coal seams is going to oxidized to generate sulfate which leads the seams continue to oxidize. The mechanism of such oxidization, its characteristics and generative conditions are significant for the detection and control of coalfield fire and its related environmental issues.
