地震勘探技术在深部找煤中的应用

成矿理论与勘探实践证明，东部一些老矿由于勘探深度、范围的限制以及认识上的局限，在矿区深部、周边仍有一些矿未能发现和查明，其中相当一部分仍具有找矿潜力；而寻找西部新的煤炭资源是国家“稳定东部发展西部”战略需要。针对中国东西部不同的地质条件和勘探目标，其地震勘探野外施工方法及资料处理原则有所差异；而资料解释在东部以查明地层赋存形态、煤层赋存范围、构造发育特征为主，西部则以寻找煤系地层波阻抗差异明显、连续性好的反射波组为解释重点。地震勘探技术在中国东西部的二个典型地震时间剖面佐证了其在深部找矿的应用效果。

Application of Seismic Prospecting Technology in Deep Part Coal Looking

Ore-forming theories and exploration practices have proved that in some old coalmines in eastern China because of limitations of exploration depths, scope and confined understandings, certain resources in deep part or periphery of those old coahnines are still fail to be found and identified, quite a part of them still have prospecting potential. While to find new coal resource in western China is the request of state strategy ＂to stabilize eastern part and develop western part＂. In allusion to different geological conditions and exploration targets, their seismic prospecting field operation methods and data processing principles have somewhat different. In eastern China, data interpretation gives priority to identify strata occurrence configuration, coal seam hosting extent and structural development characters, while in western China is emphasized on to find out composite reflection waves of coal measures strata with obviously different wave impedance and good continuity.
