唐口煤业9301工作面“绿色”充填开采技术

摘要

Pick to this paper describes the filling principle and related filling technical requirements the first filling mining working face -9301 working face in TangKou coal company, and discusses the gob roadway technology scheme and the cut support technology scheme to meet the requirements of 9301 filling working face ventilation when advancing 3.5m, by the filling mining the subsidence of 9301 working face is small, and the damage level of the ground surface construction (structure) is in the range of mild level.%本文叙述了唐口煤业公司首个充填开采工作面-9301工作面的充填原理及相关的充填技术要求，并且论述了沿空留巷技术方案以及为满足9301充填工作面通风要求而进行的工作面推进3.5m时的切眼留巷技术方案。预计9301工作面通过的充填开采，下沉较小，地表建（构）筑物采动损害等级均在轻微的Ⅰ级采动损害范围内。
