区域性防治煤与瓦斯突出研究

在煤矿生产中,随着开采深度的增加,煤层的瓦斯含量、瓦斯压力都呈上升趋势,发生煤与瓦斯突出的危险性加大,给煤矿安全生产带来很大威胁.论文以中平能化集团天安五矿地质条件为例,通过瓦斯敏感指标临界值跟踪考察及结果分析,得出瓦斯敏感指标临界值,为区域验证及局部防突提供了理论基础,并应用于工程实践,实现了快速安全掘进.

Regional Prevention of coal and gas outburst

In coal production,with the increase of mining depth,seam gas content,gas pressure in an uptrend,the occurrence of coal and gas outburst risk increased,to the great threat to mine safety and production.Thesis Zhong Ping Energy Chemical Group Tian＇an fifth ore of conditions for example,through the tracking of critical value of gas-sensitive investigation and results analysis,the critical value of gas sensitive index for regional and local validation provides a theoretical basis for conflict prevention,and applied Engineering practice,to achieve a fast and safe driving.
