摘要
浅埋煤层高强度开采易诱发严重的开采沉陷灾害。为了分析浅埋煤层开采后地表沉陷特点,防治开采沉陷灾害,在马营煤矿9102综放工作面布置地表移动观测站,采用测回法,按照闭合测量路线进行动态变形监测,探讨了浅埋煤层地表移动动态特征。
High-intensity mining of shallow coal seam is easy to induce serious mining subsidence disaster.In order to analyze the characteristics of earth surface subsidence after shallow coal seam mining,to prevent mining subsidence disaster,the earth surface movement observation station is arranged on the 9102 working face of Maying coal mine.The dynamic deformation monitoring is carried out according to the closed measurement route by using the detection method,and the earth surface movement dynamic characteristics of shallow coal seam is researched.
