摘要
孤岛工作面开采容易引起矿压显现现象,围岩及顶板的支护难度较大,且维护费用较高。本文以西山煤电集团斜沟矿10203工作面地质条件为背景,通过数值模拟方法,对采用爆破预裂切顶卸压技术的最佳切顶角度和切顶高度进行研究,经现场验证,所选用的切顶卸压参数合理、效果显著。
Mining for island working face often causes strata behavior, the support of surrounding rock and roof is difficult, and the maintenance cost is high. Based on the geological conditions of the 10203 working face in Xiegou Coal Mine, this paper studies the optimum cutting angle and height of roof by means of numerical simulation. The field test shows that the selected parameters are reasonable and the effect is remarkable.
