宁夏香山含煤区找煤方向及前景探析

宁夏香山含煤区掩盖面积大，勘查程度低，空白区多。通过对已有地质资料分析，线驮石煤矿区边界断层为倾向北东的正断层，在东部土坡组露头附近有一倾向南西的正断层，两断层形成地堑使区内的含煤地层得以保存。根据矿区边界断层以西勘查资料推测，断层以东至土坡组露头区域太原组发育较稳定的中厚煤层及部分不稳定的厚煤层，煤种为无烟煤，全区可采煤层预测资源量约3．8亿t，此外在深井预测区以西大范围掩盖区也可能赋存可观的煤炭资源，如果上述两区资源量得以证实，将会改变对香山含煤区煤炭资源的评价。

Probe into Coal Looking Orientation and Prospect in Xiangshan Coal-bearing Area, Ningxia

Large area of the Xiangshan coal-bearing area in Ningxia is covered, more than that, the degree of exploration is low and many barren sectors in. Analysis based on available geological data, the west boundary fault of the Xiantuoshi mine area is a normal fault dip NE, near the Tupo Formation outcrop in the east has a normal fault dip SW, the two faults has formed a graben, so that the coal-bearing strata in the area can be conserved. Speculation based on exploration data in the west of the boundary fault, in the Taiyuan Formation to the east of the fault up to Tupo Formation outcrop, developed rather steady medium thick coal seams and partly unsteady thick coal seams, coal rank is anthracite, with predicted mineable resources about 380 million tons in the total area. Besides, in the large covered area to the west of the deep mine prediction area may have considerable coal resources existed. If the resources in the above two areas can be confirmed, the coal resources assessment in Xiangshan coal-bearing area will be transfigured.
