煤矿井下钻探装备和钻探施工技术发展与探索

Development and exploration of underground coal mine drilling equipment and drilling construction technology

我国井下钻探装备经历了机械立轴钻机、全液压钻机和智能化钻机3个发展阶段,提高了井下特定环境下钻探安全可控程度和施工效率,但仍面临软岩钻进难题。开滦矿区结合自身大水、高瓦斯等矿井地质特点和矿井发展定位,引进国内外先进钻探装备和技术,探索实践综合配套钻探技术方法。

Underground drilling equipment in China has gone through three stages of development:mechanical vertical shaft drilling rigs,fully hydraulic drilling rigs and intelligent drilling rigs,which have improved the safety control and construction efficiency of underground drilling in specific environments,but still face the problem of soft rock drilling.Kailuan Mine combines its own geological characteristics of large water,high gas and other mines and mine development positioning,introduces advanced drilling equipment and technology from home and abroad,and explores and practices comprehensive supporting drilling technology methods.
