大倾角综放工作面支架失稳机理

Analyzing the destabilization of the hydraulic support at high-dip fully-mechanized longwall face using sublevel caving method

在大倾角倾斜煤层进行综放开采 ,支架的防倒、防滑成为决定放顶煤开采成功与否的关键。论文通过对鹤壁二矿在倾角 31°煤层使用轻型支架进行放顶煤开采试验的总结 ,分析了大倾角倾斜煤层综放开采支架失稳的机理 ,制订了支架防倒、防滑的技术措施 ,为类似条件下进行放顶煤开采提供理论依据。

Using hydraulic supports in heavy grade longwall face with sublevel caving,anti-topple and antiskid are the key factors.On the base of the test of using hydraulic supports in longwall face with sublevel caving which dip angle of coal seam is 31°,authors analyze mechanism on hydraulic supports destabilization,and make out control methods of anti-topple and antiskid.
