摘要: 分析了我国煤炭资源赋存和生产现状,指出我国煤矿已经进入深部开采,并很快进入千米以下开采时代,深部矿井建设将呈现大型化、集约化和现代化趋势。深部巷道掘进现状和困难表明:高地应力、高地温等复杂条件下,传统的钻爆法和综掘机难以满足千米深部大型煤矿快速安全建设的要求。基于深部巷道实际情况和TBM在其他地下工程中所展现的各种优势,提出将TBM 应用于深部煤矿建设,并回顾了已有的TBM 在煤矿中的应用案例。鉴于深部岩体赋存环境及其力学行为的复杂性,指出了TBM 应用于深部煤矿建设的一系列关键问题。

Abstract: The article analyzed the present situation of reserves of coal resources and exploitation, and presented that the coal mine in China had come into the time of deep exploitation and would soon come into 1000-meter-below exploitation time, when the construction of deep coal mine would have the tendency of upsizing, intensification and modernization. The status quo and difficulty of excavation in deep roadway showed that the traditional drilling and blasting method or road header can’t meet the requirements of safety and fast-speed in construction of large-scale deep coal mine below 1000 meters under complicated conditions, such as high in-situ stress, high geothermal energy, and so on. Based on the real situation of the deep roadway and various advantages of TBM in other forms of underground engineering, application of TBM in deep coal mine construction is put forward, and construction cases of TBM in coal mine are summarized. Finally, a series of key problems are presented based on the complexities of geological environments and mechanical behavior of deep rock mass.
