摘　　要：主焦煤矿在浅部采掘过程中矿井瓦斯涌出量较低,但随着开采深度的增加,瓦斯含量及压力具有明显上升的趋势,矿井迫切需要搞清深部区域的瓦斯赋存规律。结合矿井实际情况针对这一问题进行了研究,通过分析影响23采区瓦斯涌出的原因;研究煤层埋藏深度与瓦斯压力、含量的联系,绘制了23采区的瓦斯含量、压力等值线图;结合《防治煤与瓦斯突出细则》对该区的瓦斯突出危险程度进行了评价,划分出了无突出危险区,并给出了防治煤与瓦斯突出的技术措施。现场生产表明,研究结果符合矿井实际情况,对矿井安全生产具有一定的指导意义。In the process of shallow mining,the gas emission of the main coking coal mine is relatively low,but with the increase of mining depth,the gas content and pressure have an obvious upward trend.The coal mine urgently needs to find out the gas occurrence law of the deep area.Combined with the actual situation of the mine,this paper studies this problem by analyzing the causes of gas emission in No.23 mining area;The relationship between buried depth of coal seam and gas pressure and content is studied,and the contour map of gas content and pressure in No.23 mining area is drawn;combined with the detailed rules for prevention and control of coal and gas outburst,the risk degree of gas outburst in the area is evaluated,the non outburst risk area is divided,and the technical measures for prevention and control of coal and gas outburst are given.The field production shows that the research results are in line with the actual situation of the mine and have certain guiding significance for the safety production of the mine.
