机械化液压支架的工作状况,首先取决于它与围岩的相互作用,工作面支护速度,工作阻力特性、初撑力、推移力、推移速度等。试验表明,支架在破碎顶板下工作必须具有1.5百万牛顿/米~2的工作阻力。而靠增加泵压来提高初撑力涉及到许多因素。为了确定机械化支架液压系统与围岩的相互关系,在库兹巴斯矿区进行了开采1.3～5米煤层的工业性试验。试验表明,支架最困难的工况出现在破碎顶板。顶板冒落,
The working condition of mechanized hydraulic support depends firstly on its interaction with surrounding rock, working face support speed, working resistance characteristic, initial support force, pushing force and passing speed. Experiments have shown that the work of the scaffold must have a working resistance of 1.5 million Newtons / m ~ 2 when working under a broken roof. By increasing the pump pressure to improve initial support involves many factors. In order to determine the relationship between mechanized scaffolding hydraulics and surrounding rock, an industrial test was conducted in the Kuzwasbas mine for mining 1.3 to 5 m coal seams. Experiments show that the most difficult conditions of the scaffolding appear in the broken roof. Roof fall,
