在分析深部煤矿床就位机制和理清影响深部矿井安全高效开采各种地质因素的基础上,将深部煤矿床勘查类型划分为2类5型12亚类,讨论了不同勘查类型的地质保障任务、勘查方略与技术保障体系:新区和老矿区的深部煤炭资源勘查采取“快速扫面、筛选靶区、地面物探先行、深钻验证”方略;生产矿井深部资源勘查采取“物探先行、井下钻探验证”;采区地质条件探测实施“物探先行、长钻验证”;工作面地质条件探测实行“井下物探先行、长钻验证、短钻保证、巷探跟踪”.采取地面与井下结合的立体式勘查模式,优化配套勘查技术开展综合勘探,通过多手段相互补充与多成果互相验证,为深部矿井生产建设提供可靠的地质保障,是解决“有煤难采”问题的关键.

On the basis of analyzing the emplacement mechanism and disentangling various geological factors in-fluencing safety and high efficiency mining of deep coal mine, the deep coal deposit exploration types are divided into 2 categories and 5 types and 12 subtypes, also the geological guarantee task, exploration strategy, technical guarantee system of different exploration type are discussed respectively. As the exploration strategy,“rapid scan-ning, screening the target area, ground geophysical prospecting in advance, drilling verification”can be used in the new-deep developed areas and deep part of old mining areas, “geophysical prospecting in advance, underground drilling verification” can be adopted to explore the coal existing in the deep part of production coal mines, “geo-physical prospecting in advance, long borehole verification”is the effective strategy to detect geological conditions in mining areas, “underground geophysical prospecting in advance, long borehole verification, short borehole guarantee, lane detection tracking ” can be used for detecting the geology conditions of working face. In order to overcome the difficulties in mining deep coal, the key way is to use stereo exploration model combining ground and underground, to select effective exploration technology to carry out comprehensive exploration, to supply each other the multiple means , to validate each other the results, and to provide reliable geological guarantee for pro-duction and construction of deep mine.
