基于矿压监测数据的回采工作面支架适应性研究

Research on Adaptability of Support in Working Face Based on Ground Pressure Monitoring Data

通过收集干河煤矿2-116工作面顶底板岩性资料,构建了覆岩基本顶结构平衡模型,对顶板破断参数及其对支架的载荷进行了分析和计算,确定了2-116工作面基本顶层位,通过现场实测数据分析,明确了基本顶的来压规律及支架受载特征,并进行了支架对2-116工作面覆岩运动的适应性评价。研究结论表明,2-116工作面支架选型准确,工作阻力适中,符合工作面顶板岩层控制的要求。

The equilibrium model of basic roof structure of overlying strata is constructed of Ganhe coal mine 2-116 working face.The roof breaking parameters and the load on the support are analyzed and calculated.The basic top layer of 2-116 working face is determined.Through analysis of field measured data,the weighting law of the basic roof and the loading characteristics of the support are clarified.The adaptability of support to overburden movement in 2-116 working face is evaluated.
