【摘要】 煤房煤柱是房柱式采煤法的基本结构,同时煤房煤柱设计也就是房柱式采煤法岩层控制的核心。煤柱具有足够的强度,才能够保证支护空间的稳定。神府东胜矿区浅埋深薄基岩下柱式体系采煤法存在着一定的问题,以霍络湾矿为例,由于采用小尺寸煤柱不能满足长期稳定的要求,所以需要针对其特点进行工作面布置参数优化研究。 本文着重对两类煤柱进行研究,一类是区内支撑煤柱,作用是在小区域开采期间支撑顶板,采后能够及时垮落;另一类是隔离煤柱作用是有效地隔离一个较小的开采区域,使顶板不能形成连续垮落。在数值模拟与现场实测研究的基础上提出霍络湾矿工作面布置参数优化方案。更多还原

【Abstract】 Room and coal pillar are the fundamental structure of room and pillar method. The design of Room and coal piljar is the core in the room and pillar method. Only coal pillar has enough strength, it can ensure the stabilization of the support. Pillar mining method under shallow depth of burial and thin bedrock in Mine of ShenFu and DongSheng has some problem, for example of HuoLuoWan mine, Because the coal pillar are small and can’t satisfy the need of secular stability, we must study the parametric optimization of working face.This thesis lay stress on two sorts of coal pillar. One is coal pillar inside the area, the function of it is to support rock layer above the ore bed during mining, and can collapse in time after mining. The other sort of coal pillar is partition coal pillar, the function of it is to close off a smaller mining area and make the rock layer above the ore bed can’t collapse continuously. On the basis of numerical simulation and observation in situation , we bring forward the project of the parametric optimization of working face.更多还原
