摘要
为了探究分析工作面断层矿压的显现规律以及特征,针对某矿81308工作面的回采巷道进行研究,采用数值模拟方法,通过建立数值模型分析工作面在距采空区较近时的矿压规律,提出过断层优化方案,使煤层的开采安全得到保障。现场监测结果表明,实测顶板下沉量为65.8 mm,断层最大滑移量为75 mm,经济效益明显,实现了工作面的安全高效回采。
In order to explore and analyze the manifestation law and characteristics of the fault pressure in the working face,a study was conducted on the mining roadway of the 81308 working face in a certain mine.Numerical simulation methods were used to establish a numerical model to analyze the pressure law of the working face when it is close to the goaf,and an optimization plan for passing through the fault was proposed to ensure the safety of coal seam mining.Through on-site monitoring,the results show that the measured subsidence of the roof is 65.8 mm,the maximum slip of the fault is 75 mm,and the economic benefits are significant,achieving safe and efficient mining of the working face.
