摘    要:以支架与顶板相互作用关系为理论依据,通过数值模拟方法分析了综放工作面顶煤下沉量及顶煤压缩量与支架支护强度的关系,在此基础上根据顶板条件的不同对综放工作面支架工作阻力进行确定。

关 键 词:综放开采  支架工作阻力  数值模拟

Abstract:Based on the theoretical correlation between the power supports and the roof, the relations of subsidence and compression distance of top coal with supporting strength of power supports are analyzed by numerical simulation. According to the condition of the roof, the working resistance of top coal caving power supports can be calculated.
Keywords:longwall top coal caving  working resistance  numerical simulation
