超高水材料充填技术在陶一矿开采中的应用

Application of filling technology with super high-water materials in coal mining in Taoyi Coal Mine

针对陶一煤矿建下压煤问题,论述了开采技术方案,对充填试验面进行了沉陷预计分析。为保证建下压煤工作面的安全生产,采取超高水材料充填新技术对工作面采空区进行充填,并对充填开采地表沉降变形规律进行了监测与研究,以保证铁路在采煤过程中的正常运行。

Aiming at the problem of coal under braidings in laoyt wue, L ~, technical proposals were discussed, and the subsidence of filling test surface was predicted and analyzed. In order to guarantee the safety mining under buildings, the new filling technology with super high-water materials was applied in the goal of filling mining face, and the subsidence and deformation laws of ground surface were monitored and studied, which ensured the normal running of railway in process of mining.
