基于应变原理研发的高精度支架工作阻力监测系统,应用于付村煤矿综采面液压支架工作阻力实时监测,分析得出工作面直接顶来压步距为18.5m,基本顶初次来压步距平均为36.5m,基本顶周期来压步距平均为10.5m;支架选型基本合理,富余系数较大,在工作面没有特殊构造的条件下,ZY6400—25/53型掩护式液压支架能够满足顶板来压的要求;所采用的监测方法可为类似工作面的矿压观测工作提供借鉴。
Based on the principle of strain developed high-precision support work resistance monitoring system, used in Fucun coal mine fully mechanized mining hydraulic support working resistance real-time monitoring, analysis of the work surface direct top pressure step is 18.5m, the basic top pressure step An average of 36.5m, the basic top cycle to step average distance of 10.5m; stent selection is reasonable, with large coefficient of surplus in the face without special conditions, ZY6400-25 / 53 type of protective hydraulic support to meet Roof pressure to the requirements of the monitoring methods used for similar work face pressure observation work to provide reference.
