为了解水城矿区隔档式褶皱对该区域煤与瓦斯突出灾害影响问题,采用理论分析、现场考察等手段研究了水城矿区隔档式褶皱演化分析及其对煤与瓦斯突出灾害影响机理及特征.研究表明:水城矿区先期断裂存在及燕山期挤压力学作用形成了水城矿区隔档式褶皱,背斜区域造成煤层及瓦斯缺失,向斜区域煤层及瓦斯得以保存,隔档式褶皱形成过程中由于层间滑动、沿断裂滑动等造成了煤系地层破坏,形成了构造煤,挤压应力环境形成了瓦斯封闭系统,造成了瓦斯富集,越靠近向斜轴部,煤与瓦斯突出次数越多,灾害越严重.
In order to understand the influence of barrier fold in Shuicheng mining area on coal and gas outburst disasters in this area, theoretical analysis and field investigation were carried out to study the mechanism and characteristics of barrier-type fold evolution in Shuicheng mining area and its influence on coal and gas outburst disasters. The results show that the pre-fractures in Shuicheng mining area and the Yanshanian extrusion mechanics formed the pad-fold in Shuicheng mining area, the coal seam and gas loss in the anticline area, the coal seam and gas in the syncline area were preserved, Layer sliding, sliding along the fault caused by coal seam stratigraphic damage, the formation of tectonic coal, compressive stress environment formed Gas closed system, resulting in gas enrichment, the closer the syncline axis, the more the number of coal and gas outburst , The more serious disaster.
