山东裕隆矿业集团唐阳煤矿主采3下煤层。煤层倾角约15°,厚度5.6~6.8m,地质条件复杂,断层较多,尤其工作面中部沿走向方向地应力较集中,断层密集且相互交错。煤层厚度变化较大,煤层结构复杂,一般含1-2层夹矸。自投产以来,一直采用分层倾斜长壁采煤法,工作面采用单体支柱配金属铰
Shandong Yulong Mining Group Tangyang coal mining 3 under the main coal. The coal seam inclination is about 15 ° and the thickness is 5.6-6.8m. The geological conditions are complex and there are many faults. In particular, the central part of the working face is more concentrated along the strike direction and the faults are dense and intertwined. Thick seam thickness changes, the coal seam structure is complex, usually containing 1-2 layers of gangue. Since put into production, has been the use of stratified inclined longwall mining method, the face of the single prop with metal hinges
