急倾斜煤层液压支架稳定性分析和控制措施

Stability Analysis and Control Measures of Hydraulic Supports in Steep Coal Seam

从静力学角度对急倾斜煤层工作面液压支架的抗倾覆、滑移稳定性进行了分析,根据理论分析并结合急倾斜煤层的实际工况,从支架自身结构提出了相应的控制措施,使支架的使用更适应于急倾斜煤层综采。

The anti-toppling capacity and the sliding stability of the powered supports used m steep coat seam on the basis of statics were analyzed. According to theoretical analysis and taking into consideration of the actual working conditions of the steep coal seam, puts forward corresponding control measures at aspect of the structure of the powered supports so as to make the powered roof supports more adaptable to the fully-mechanized mining of steep coal seam.
