新汶矿区深部冲击地压防治技术研究

Study on Bump Protection Technology in Deep Part of Xinwen Mine Area

摘要:

冲击地压是世界范围内煤矿生产中最严重的自然灾害之一。新汶矿区的开采深度较深，冲击地压是矿井安全生产的一个严重威胁。该文针对孙村矿二、四层煤层及其围岩，建模分析了在不同采动条件下地应力分布规律和发生冲击地压的危险程度，并根据分析结论，提出了在实际采矿作业中应采取的解危方案和综合防治措施。

Abstract:

Bump is a dangerous hazard in coal mine production all over the world. Mining depth in Xinwen mine is very deep and bump is a great threaten to safe production. Pointing to No.2 and No.4 coal strata and country rocks in Suncun mine, distribution rule of earth stress in different mining conditions and damage degrees of bump happening are analyzed. According to analysis conclusion, protection countermeasures which will be used in exploration are put forward in this paper.
