大同矿区冲击地压典型影响因素组合分析

Analysis on Typical Influence Factors Combination of Coal Bumps in Datong Mining Area

以大同矿区坚硬煤岩组合条件下采动影响区域冲击地压发生的时空特征为背景,针对典型坚硬煤岩层组合和多煤层高强度开采条件,采动应力诱发煤层在煤岩组合结构中的滑移失稳是冲击地压频发的主要模式。通过分析典型冲击矿井发生冲击的时空特点,明确了冲击地压发生的典型组合因素,可为后续有针对性的灾害防治提供参考。

The engineering background of the current application is the temporal and spatial characteristics of Datong mining area coal bumps caused by mining effect under the condition of hard coal-rock structure. Focusing on the compound structure of coal-rock and complex geological condition, structural slip instability of coal bumps caused by mining effect is the most frequency instability mode. By analyzing behavior characteristics of coal bumps in typical mines, the typical factors of coal bumps is learned, and it can provide support for following hazard control.
