急倾斜综采采煤方法及工艺设计研究

Study on Method and Technology Design of Sharp Inclined Fully Mechanized Mining

内蒙古乌仁都西煤矿设计批复先期为露天开采,后期为井工开采。现煤层开采至+1555m标高,结合生产实际,经开采成本经济论证,再往下开采,煤层剥采比较大,成本较高,经济效益较差。该矿+1555m以下变更为井工开采方式。但是该矿煤层倾角大,因此进行大倾角综采采煤方法和采煤工艺的研究极其重要。

The design approval of Wurendui West coal mine in Inner Mongolia is open-pit mining at the early stage and underground mining at the later stage.Coal mining is now+1555m elevation,combined with the actual production,the cost of economic feasibility studies,further down the mining,mining stripping larger,higher cost,poor economic efficiency.The mine+1555m following the change to the underground mining methods.However,due to the large dip angle of the seam,it is extremely important to study the coal mining method and coal mining technology at high dip angle.
