综采工作面过断层回采工艺技术研究分析

Analysis on Technology of Cross Fault Mining in Fully Mechanized Mining Face

基于综采工作面在揭露断层时受构造应力、回采应力以及上覆岩层重力等作用下,煤体破碎、片帮,导致工作面端面距加大、支护难度大、局部冒落等现象,降低了工作面回采效率,威胁回采安全。隆安煤业通过技术研究,分析了综采工作面在过断层期间主要存在的技术难题及常见过断层回采工艺,取得了显著应用成效。

When fully mechanized working face is exposed to faults,under the action of tectonic stress,mining stress and the gravity of overlying strata,the coal body is broken and spalling,which leads to the increase of end face distance,difficult support and local caving,which reduces the mining efficiency and threatens the mining safety.Through technical research,Longan Coal Industry analyzed the main technical problems and common fault crossing mining technology of fully mechanized working face during fault crossing,and achieved remarkable application results.
