人工假顶在工作面应力冒落区中的应用

Application of Artificial Roof in Stress Caving Zone of Working Face

受构造应力、回采应力等集中超前应力破坏作用,8103工作面运输顺槽顶板出现冒落区,造成工作面移架时出现不接顶、支架初撑力及工作阻力不足等现象,影响工作面安全高效回采。对人工假顶在工作面应力冒落区的应用进行了探讨。通过实践,人工假顶的应用解决了支架不接顶技术难题,支架初撑力、工作阻力提高至87%以上。

Due to the destruction of structural stress,mining stress and other concentrated leading stress,caving area appeared in the roof of 8103 working face transportation trough,resulting in the phenomenon of no roof connection,insufficient support force and working resistance in moving support in the working face,which affected the safe and efficient mining of the working face.This paper discussed the application of artificial roof in stress caving area of working face.Through practice,the application of artificial roof solved the technical problem of support not connected with roof,and the initial support force and support working resistance were increased to over 87%.
