特厚、突出、极松软、大应力、极复杂地质条件下跟煤底施工技术研究

Thick, Prominent, Very Soft, High Stress, Very Complicated Geological Conditions Construction Technology with Coal Bottom

青东矿82采区8煤层首采工作面为828工作面，煤层厚度6．2～13．2m，平均厚度为9．2m，回采工艺为综放，工作面巷道施工采取跟底留顶煤施工，由于煤体松散破碎，同时过上覆726工作面收作线应力集中区、频繁过断层、过构造，在施工期间遇到很多了困难，特别是极松散的煤顶在超前管理上、支护上，和现场施工管理上采取非常有价值的举措，成功的克服了各种困难，巷道单进达100m／P]，减少了工作面准备时间，回提前回采产出的煤炭而带来巨大的经济效益和社会效益。

Green East Mine 82 coal mining area 8 828 First Mining Face Face, seam thickness 6.2 - 13.2m, an average thickness of 9.2m, caving mining processes, taken with the end face roadway construction remain top coal construction, because coal body broken loose, but too close for the overlying line 726 face stress concentration area, frequently through fault, over-construction, during construction encounter many difficulties, especially very loose coal roof in advance managemen{~ support, and and on-site construction management to take a very valuable initiative, successfully overcome various difficulties, the roadway Shan Jin of 100m / month, reducing the face preparation time, back to the early coal mining output and bring huge economic benefits and social benefits.
