综放工作面托煤顶锚网支护技术研究与实践

Fully Mechanized Working Face Support Top Coal Anchor Net Supporting Technology Research and Practice

开滦范各庄矿业分公司2529N工作面区域为12煤层与12下煤层合区,平均煤厚6m,设计采用综采放顶煤开采工艺。为保证工作面的安全高效回采,工作面通风巷、运输巷及切眼掘进时采用托煤顶锚网支护。根据巷道围岩条件,采取有针对性的支护对策,取得了较好支护效果,为综放工作面托煤顶锚网支护提供了强有力技术支撑。

Fangezhuang Mining Branch 2529N working area was No.12 coal seam and No. 12 T coal seam, with average coal thickness 6 m, fully mechanized caving top coal mining was adopted. In order to ensure the safe and efficient working face mining, support top coal anchor net supporting was adopted when mining in ventilation roadway transportation lane and cut eyes. According to the conditions of roadway surrounding rock, targeted support measures were adopted, with good support effect, which provided strong technical support for fully mechanized working face support top coal anchor net supporting.
