针对田庄煤矿村庄下压煤严重制约矿井的正常生产接续的现实,提出了超高水材料充填采煤技术。介绍了超高水材料充填工艺的具体流程。工作面按面长50 m布置,采20 m留10 m煤柱,采用“两采一充”的连续充填开采模式。通过对充填效果进行理论的分析,预计在充填条件下,地表下沉最大值430 mm,水平移动最大值100 mm,倾斜最大值1.8 mm/m,建筑物全部为I级破坏。
Aiming at the fact that coal mines in Tianzhuang coal mine seriously restrict the normal production of coal mines, the paper puts forward the technology of coal filling with ultra-high water materials. Introduced the ultra-high water material filling process specific process. The working face should be arranged according to the face length of 50 m and the 20 m coal pillar should be retained for 10 m. The continuous filling mode of “two mining and one charging” should be adopted. According to the theoretical analysis of filling effect, it is estimated that under the conditions of filling, the maximum of surface subsidence is 430 mm, the maximum horizontal displacement is 100 mm and the maximum inclination is 1.8 mm / m. The buildings are all Grade I damaged.
