为揭示阳煤一矿S8310大采高综采面煤壁片帮规律并提出有针对性的控制措施,避免盲目治理和减少成本投入,从理论上分析了工作面煤壁片帮的形式和影响煤壁片帮的因素。通过数值模拟,以煤壁片帮深度为参考比较对象,研究了煤壁片帮与煤体硬度、支护强度以及俯(仰)采的关系,并确定了这3种影响煤壁片帮因素之间的主次关系。俯采对控制煤壁片帮效果最好,提高煤体硬度和增大支护强度2种方法控制效果相近,基于此,制定了该工作面的煤壁片帮控制措施。
In order to reveal the rule of coal wall slab in S8310 high mining height fully mechanized coal face of Yangci No.1 Mine and put forward some control measures to avoid blind control and reduce cost investment, the form and influence of coal wall slab in working face are analyzed theoretically Coal wall to help the factors. Through the numerical simulation, taking the depth of coal wall slab as a reference, the relationship between the coal wall slab and the hardness, supporting strength and pit (Yang) mining was studied, and the three factors affecting coal wall slagging were determined The primary and secondary relations between. The results show that the control measures of the two methods are the best, the control measures are the best to control the coal wall slab, the coal wall hardness is increased and the support strength is increased.
