【摘要】 随着我国的煤炭形势好转,煤矿采煤技术和采煤方法得到不断更新,采煤机械化水平也不断提高,采煤工作面推进速度提高到150～250m/月,甚至更高,而岩巷掘进速度却一直停留在较低的水平,使采掘接续普遍紧张。主要是由于矿井机械化程度仍然不高,支护优化不好,且工艺组织不够合理,掘进速度受到一定的限制。因此,研究岩巷高速高效掘进施工具有重要的理论价值和工程意义。本文在总结分析前人研究成果的基础上,从施工工艺、掘进设备、地质条件及施工组织管理等方面对岩巷高速高效掘进施工的影响因素进行了理论分析和总结,并在此基础上为实现岩巷高速高效掘进施工提出了可参考的技术措施。在具体煤矿的实践应用中,全面开展了提高岩巷掘进速度的具体技术研究,其中主要包括:通过岩石力学性能测试分析和数值模拟,优化巷道支护方案;进行岩巷掘进设备综合配套研究;开展岩巷高速高效施工方案设计和劳动组织研究,提出并应用了“三掘三喷”新工艺;应用了新型的自燃陶粒土喷浆材料:开展研究裂隙岩体爆破研究,并以此为基础,进行了爆破钻孔布置的优化设计;应用了刚性风筒长距离通风技术等,取得了良好的经济效益和社会效益。更多还原

【Abstract】 As the situation of our country’s coal is better, the coal-mining technology and the coal-mining method and mining mechanization obtain the unceasing renewal, the speed of the process of advancing coal face is increased to 150～250 meter per month,or even higher. But the rock drivage speed is kept at low level, which generally made the mining continuing difficult. Principally because the mechanized degree of mines is not still high, the support optimization is bad, also the craft organization insufficiently is reasonable, drivage velocity have been restricted. So the study of rock tunnel drivage with high-efficiency and high-speed has important theoretical value and engineering significance.Based on the previous research results, the analysis and the conclusion of the influence factor of rock tunnel drivage with high-efficiency and high-speed are carried out from the construction craft, the tunneling equipment, the geological condition and the construction organization management and so on. They offer the technical measures to rock tunnel drivage with high-efficiency and high-speed. In a concrete practice of a coal mine, overall the specific technical research of the rock drivage speed are developed, which mainly concludes tunnel support optimization scheme from test analysis of the rock mechanics property and numerical simulation, the research of mechanized equipment in the rock drivage, the research of scheme design and labor organization in rock tunnel drivage with high-efficiency and high-speed, a new applied process of "three times of excavations and gunites", a new application of "autoignition ceramisite gunniting material", the optimization drilling and blasting method, the application of rigid fan drum for long distance ventilation, which obtain the good economic and social profits.更多还原
