| 摘 要： | 分析了影响淮北煤田煤与瓦斯突出的地质因素主要为区域构造、深度、围岩性质、断层、煤层厚度变化、煤层结构变化;提出了适合淮北地质条件的防突措施为地面钻孔预抽突出煤层瓦斯、开采保护层、钻孔超前卸压排放、石门多循环解突揭煤、突出煤层近距离岩巷掘进、立井揭煤等.

| Abstract: | The paper analyzed the geological factors of the coal and gas outburst in Huaibei Coal Field.The geological factors were including the area structures,depth,surrounding rock properties,faults,variation of seam thickness and seam structure variation.The paper provided the outburst prevention and control measures suitable to Huaibei geological conditions.The measures were including the gas pre-drainage from seam with boreholes at surface,mining protection layer,pressure releasing and discharge with pilot boreholes,cross-cut multi circulation to release outburst when seam opened,mine roadway excavation with a close distance with seam in potential outburst,mine shaft sinking through seam and others. |
