【摘要】：平煤十矿构造控制瓦斯及其灾害特征明显,以此为例,进行典型瓦斯主控构造特征和分析。原十一矿逆断层及其反冲断层控制了平煤十矿的瓦斯分带和瓦斯灾害分布,是平煤十矿瓦斯主控构造。通过大量实际生产工作面瓦斯涌出量数据统计,按构造控制区域将十矿划分为4个单元,浅部低瓦斯区工作面相对涌出量为1.59 m3/t,十矿向斜高瓦斯区工作面相对涌出量为16.87 m3/t,郭庄背斜低瓦斯区工作面相对涌出量4.20 m3/t,李口向斜高瓦斯区工作面相对涌出量15.73 m3/t。根据主控逆断层两盘的应力分析,通过对瓦斯相关参数统计,结合瓦斯灾害事故分布情况,讨论主控构造对瓦斯灾害分布控制,提出今后重点瓦斯灾害防治区。
[Abstract]:The characteristics of gas control and its disaster in Pingmei No. 10 coal mine are obvious, and the characteristics and analysis of typical gas main control structure are carried out as an example. The reverse fault and its recoil fault control the gas zoning and gas disaster distribution in Pingmei No. 10 Mine, which is the main gas control structure in Pingmei No. 10 Mine. Based on the statistics of gas emission in practical working face, the tenth coal mine is divided into four units according to the structural control area. The relative emission amount of working face is 1.59 m3 / t in shallow low gas area, 16.87 m3 / t in high gas area of No. 10 mine syncline, 4.20 m3 / t in working face of low gas area in Guozhuang anticline, and 15.73 m3 / t in high gas area of Likou syncline. According to the stress analysis of the two plates of the main control reverse fault, through the statistics of the gas related parameters and the distribution of the gas disaster accident, this paper discusses the distribution control of the main control structure to the gas disaster, and puts forward the key gas disaster prevention and control area in the future.
