摘要
以古汉山矿19上仓皮带巷揭煤为工程背景,采用理论研究、工程类比和地面模拟相结合的研究方法,通过严格落实区域防突措施、合理设计石门揭煤导硐长度和远距离爆破网络优化等技术和管理措施,进一步完善了石门揭煤的程序。现场应用过程中,有效地保障了揭煤区域的抽采达标和远距离安全爆破,实现石门揭煤区域的安全快速揭煤。
The paper presents the process of improving the crosscut coal uncovering by regional outburst prevention measures,reasonable design of the length of the pilot tunnel and long-distance blasting network optimization and simulation based on the theoretical research,engineering analogy and ground simulation,which can effectively ensure the extraction and long-distance safety blasting and realize the safe and quick coal uncovering in the coal-uncovering area.
