摘要
在现场观测基础上，分析了两硬（坚硬顶板，坚硬煤层）综放采场来压情况；运用回归分析，得出支架初撑力和循环最大工作阻力间的关系，由此给出确定放顶煤支架合理工作阻力的方法。
Based on the spot observations,this paper analyzes the strata behaviors of fully mechanized face under the double hard conditions.With the help of regression analysis,the relationship between setting load and time weighted maximum resistance of support has obtained.Thus,a way of determining the reasonable working resistance of support is given.
