支撑掩护式液压支架与覆岩作用力分析

Analysis on Acting Force between Chock-Shield and Overlying Strata

根据砌体梁学说,确定了综采工作面液压支架工作阻力,论述了支撑掩护式液压支架与覆岩作用关系,并对支架在覆岩作用下立柱受力情况进行力学分析。结合实际使用情况,提出了提高支撑掩护式液压支架对顶板适应性的措施。

According to the theory of masonry beam, ensured support resistance in fully mechanized coal mining face, discussed the relationship between chock - Shield and Overlying Strata, analyzed the prop force of the support under the overlying strata by mechanics method. Based on the actual usage, put forward the measures of improve the adaptability to roof rock of the chock - shield.
