近距离煤层煤柱高应力下巷道支护技术研究

Research of Support Technology under High Stress Coal Pillar with Short Range

文章通过研究煤柱下高应力巷道顶板及两帮的变形机理和破坏情况,确定高应力作用下巷道的支护方式为强力锚杆锚索组合支护。该技术成功地应用于潞安集团某矿的巷道支护中,取得了良好的技术效果和经济效益,可以在类似条件下的煤柱高应力巷道中推广应用。

Through high stress under the coal pillar of roof and deformation mechanism and damage,we determined the high stress under the action of roadway supporting method for powerful bolt anchor combined bolting. This technology has been used in a group of roadway support, has obtained the good technical effect and economic benefit in similar conditions of high stress in coal pillar of application.
