摘要
通过安装在105工作面支架上的压力记录仪监测的数据,合理分析了工作面顶板矿压特点以及ZF13000/25/38型液压支架在使用过程中承载特性,明确了工作面在回采期间初次来压步距、周期来压步距以及动载系数,确立ZF13000/25/38型液压支架各项参数满足生产需要,为后期工作面在推进过程中出现的顶板压力变化能够及时校准液压支架各项参数提供实测依据。
Through the installation of the 105 working face support pressure recorder monitoring data, reasonable analysis of roof strata and characteristics of ZF13000/25/38 type hydraulic support in the process of using the bearing characteristics, the working face in mining during the first weighting, the periodic weighting step distance and dynamic load coefficient, the establishment of ZF 13000/25/38 type hydraulic parameters the support to meet production needs, provide reference data and calibration parameters for hydraulic roof pressure changes late working face in the process of advancing to.
