关于永佛寺煤矿8号煤回采工作面瓦斯抽采方案的研究

运用关于瓦斯抽采的各种研究理论,结合永佛寺煤矿瓦斯地质情况,对一水平下部8号煤层开采时的瓦斯及煤与瓦斯突出造成的影响进行了分析,并提出了治理方案,即运用卸压抽采和未卸压抽采相结合的方法,通过计算确定了抽采参数,预计可以达到良好的抽采效果。

Study on Gas Extraction Scheme Adopted by the Coalface of 8th Seam in Yongfosi Coalmine

By using various research theories of the gas extraction,and connecting with the gas geological condition of Yongfosi Coalmine,this paper makes analysis on the influences caused by the gas and the coal/gas outburst when a horizontal underpart of 8th Seam is mined,and puts forward a treatment scheme;Combining gas extraction with pressure relief and gas extraction without pressure relief,determines the extraction parameters through calculation,and estimates that the excellent extraction results can be achieved.
