摘　　要：针对田庄煤矿3601液压支架炮采工作面,进行了液压支架适应性研究。运用圆图自记仪监测了液压支架支柱的支护阻力及其变化过程,得到了支架的初撑力、循环末阻力和时间加权平均工作阻力,并对该工作面支架的适用性进行了分析。结果表明:ZZ2400/08/15型液压支架初撑力较低(平均初撑力远小于其额定值的80%),额定工作阻力安全系数偏小(时间加权平均工作阻力大于额定工作阻力的90%,老顶周期来压时支架平均工作阻力达到额定工作阻力的96.01%),对3601工作面顶底板支护的适应性较差。Based on the hydraulic support of No.3601 blasting face in Tianzhuang Coal Mine,the circular chart self-balance recorder was used to monitor the supporting resistance of the hydraulic support and its changing process in order to obtain the setting load,end-of-loop resistance and average time-weighted working resistance.Accordingly,the applicability of support in the work surface was studied.The results show that the setting load of ZZ2400/08/15 hydraulic support is lower with the average value much less than 80% of its rated value.The safety coefficient of rated working resistance is smaller(the average time-weighted working resistance is greater than 90% of the rated value and the average working resistance of the support reaches 96.01% of the rated value during the periodic weighting in the goaf)with the poor adaptability to the roof and floor supporting of the 3601 working face.
