麦捷煤业山底铺村合理保护煤柱留设方法浅析

Research and application of mechanical properties of static breaker

目前麦捷煤业进行山底铺村保护煤柱的设计及留设的工作,为了使留设的保护煤柱面积在充分有效保护建筑物安全使用的前提下,尽可能的减少其压煤量,充分的利用煤炭资源。本文通过垂线法和垂直剖面法分别计算山底铺村保护煤柱的留设面积及压煤量,最终得出垂线法更适合山底铺村保护煤柱的设计。最终设计山底铺村保护煤柱面积为117900㎡,压煤量为1129000t。

At present, Maijie Coal Industry has carried out the design and retention work of the protective coal pillars of Shandipu Village. In order to make the remaining coal pillar area fully protect the safe use of buildings, reduce the amount of coal crushed as much as possible.Make full use of coal resources. In this paper, the vertical area and vertical section method are used to calculate the remaining area and coal volume of the protected coal pillars in Shandipu Village. Finally, the vertical line method is more suitable for the design of the protected coal pillars in Shandipu Village. Finally, the area of protected coal pillars in Shandipu Village was 117,900 m2, and the coal crushing capacity was1129000 tons.
