桑树坪煤矿煤与瓦斯突出问题研究

Study on coal and gas outburst in Sangshuping Coal Mine

煤炭是我国的主要能源,随着煤矿开采深度的增大,复合动力灾害在煤矿中出现的频率随之增加,传统单一治理瓦斯或者冲击地压已经不能很好地解决不断出现的复合动力灾害。桑树坪煤矿为煤与瓦斯突出矿井,处于瓦斯灾害严重的韩城矿区,该矿井是韩城矿区的主力矿井,其4321采煤工作面现今在区域临界指标一降再降的情况下仍然会有动力现象发生。从能量大小、局部预测与数据校检等因素分析入手,对4321工作面发生的动力现象予以判定,确定4321采面发生的动力灾害类型,为4321采面的瓦斯治理方案提供支持。

Coal is the main energy in China,and with the increase of coal mining depth,the frequency of composite dynamic disasters in coal mines increases,which makes the traditional single control method of gas or rock burst can not solve the continuous composite dynamic disasters.Sangshuping Coal Mine is a coal and gas outburst mine,which is located in Hancheng mining area with serious gas disaster.The coal mine is the main mine in Hancheng mining area,and its No.4321 working face still has dynamic phenomenon when the regional critical index drops again and again.Based on the analysis of energy,local prediction and data checking,the dynamic phenomenon of No.4321 working face is analyzed,and the type of dynamic disaster is determined,so as to provide support for the gas control scheme of No.4321 working face.
