过构造巷道支护参数设计研究

Structure of roadway support parameter design research

对井田构造发育的复杂程度进行科学评价,对于指导煤矿巷道布置、顶板支护及工作面回采等一系列开采活动具有重要的现实意义。本文根据西山煤电集团公司官地矿的地质背景,通过对其2号、3号"一掘一采"两面的过构造研究,分析确定了巷道断面二次支护的相关参数,为安全掘进提供保障。

The scientific evaluation of the complexity of mine field structure development will guide a series of mining activities such as roadway layout, roof support and working face recovery. Has important practical significance. Based on the geological background of Xishan Coal and Electricity Group Corporation Guandi Mine, through the over-construction study on its 2#and 3#＂one digging and one mining＂, this paper analyzes the coal mining driving support technology under complicated geological conditions Use, to ensure the safety of coal mining work carried out smoothly, providing a scientific basis.
