摘 要:地质构造带石门揭煤工程突出危险性大、防突技术难度大,根据矿井实际瓦斯地质条件和相关规定、要求,提前采取辅以水力割缝技术的"专用巷道穿层钻孔预抽+工作面穿层钻孔预抽"综合预抽煤层瓦斯技术措施,大大降低了揭煤的突出危险性。然后根据渐近式石门揭煤技术措施、"边探边掘、浅掘浅进"技术要求、严格规范的保障及管理措施,实现了地质构造带巷道的安全顺利揭煤,大大缩短了揭煤时间。The outburst danger of exposing coal seam in a cross-cut near geological tectonic belt is large,and the difficulty of relevant outburst prevention technology is big,too. According to the actual gas geological conditions and the relevant regulations and requirements of coal mines,comprehensive gas drainage technical measures were carried out in advance,including special roadway cross layer drilling drainage + cross layer drilling drainage on working face,hydraulic cutting seam technology was also used as cross layer drilling drainage. The application of these measures has greatly reduced the outburst danger of exposing coal. By technical measures for incremental exposing coal seam in a cross-cut,technical requirements of tunneling after detection,shallow dig shallow footage,strict and standard protection and management measures,the safe and smooth coal exposing in roadway of geological tectonic belt has been achieved,and the exposing time is greatly shorten.
