在分析我国煤炭资源分布与供需矛盾的基础上,提出中国东部深层煤矿床勘查开发的主要任务是弄清煤层赋存与分布状态,寻找煤炭资源,精细查明影响矿井生产的各种地质因素和工程技术条件。根据煤炭地质勘查技术发展现状、探测能力与精度,指出深部煤炭资源勘查技术思路是“快速扫面、筛选靶区”,勘查方略是“立体综合勘探,精细物探先行、深钻追踪验证”,即以精细三维地震和电法勘探为先导,配合其它勘查手段。深层煤矿床勘查工作模式有3个层次,完成深部煤矿床快速精细探测的根本途径是依据煤田(井田)地质背景和勘查地质目标,选取勘查方法和探测技术,实现地质、物探、钻探与地理信息系统、计算机技术的有机结合和多成果相互验证。
在分析我國煤炭資源分佈與供需矛盾的基礎上,提齣中國東部深層煤礦床勘查開髮的主要任務是弄清煤層賦存與分佈狀態,尋找煤炭資源,精細查明影響礦井生產的各種地質因素和工程技術條件。根據煤炭地質勘查技術髮展現狀、探測能力與精度,指齣深部煤炭資源勘查技術思路是“快速掃麵、篩選靶區”,勘查方略是“立體綜閤勘探,精細物探先行、深鑽追蹤驗證”,即以精細三維地震和電法勘探為先導,配閤其它勘查手段。深層煤礦床勘查工作模式有3箇層次,完成深部煤礦床快速精細探測的根本途徑是依據煤田(井田)地質揹景和勘查地質目標,選取勘查方法和探測技術,實現地質、物探、鑽探與地理信息繫統、計算機技術的有機結閤和多成果相互驗證。

Based on analyses of coal resources distribution and contradiction between supply and demand, pointed out the main tasks for deep coal deposits exploration and exploitation in eastern China have:figuring out coal seams hosting and distribution status, look?ing for new coal resources, exactly identifying various geological and technological conditions impacting coalmine production. Accord?ing to coal geological exploration technology development status quo, capability and accuracy, indicated the technical idea to explore deep coal resources is“overall scanning, target areas screening”;exploration strategy is“3D integral exploration, fine geophysical pros?pecting in advance, deep drilling tracing and verifying”, that is guiding with fine 3D seismic and electric prospecting, accompanying with other exploration means. Working mode of deep coal deposit exploration has 3 levels, basic approach to fulfill deep coal deposit quick fine prospecting is based on coalfield (minefield) geological setting and prospecting target to select method and technology of prospecting and realize seamless integration and mutual validation of multiple results from geological, geophysical prospecting, drilling, GIS and computer technology.
