摘要
通过理论计算掌握了S1304采场所需支护阻力理论值,确定ZF8000/20/38型放顶煤支架能够满足支护要求;现场实测结果表明,该型号支架实际工作状态能够满足现场支护要求;综合认为,ZF8000/20/38型号支架在S1304工作面采场适应性较好。本着控制顶板岩层下沉和离层的目的,提出应采取措施加强初撑力管理。
By theoretical calculation, the required theoretical value of supporting resistance in S1304 stope was mastered. And it is determined that the caving supports of ZF8000/20/38 model can meet the support requirements. The results of field measurement showed that the actual working status of this model of supports can meet the requirements of support on the spot. It was comprehensively considered that the supports of ZF8000/20/38 model adapt well in stope of S1304 mining face. For the purpose of controlling subsidence and separation of roof strata, it is proposed that measures should be taken to strengthen the management of setting load.
