青海省木里煤田弧山矿区东部找煤预测

通过对区内褶皱特征、控煤断层及沉积环境的分析研究，预测在木里煤田弧山矿区东部仍有煤系地层赋存。预测区内构造为一宽缓向斜，与弧山向斜共同构成隔档式（梳状）褶皱。含煤地层为中下侏罗统江仓组，成煤环境属中生代断陷盆地内河湖、沼泽相沉积。F2为弧山矿区南部边界断层，在前期控制了煤系地层的沉积，后期又控制了煤系地层的埋深和保存，预测区所处位置其煤系地层埋藏较浅，较有利于煤层的开发和利用。

Eastern Hushan Mining Area Coal Looking Prediction in Muri Coalfield, Qinghai Province

Analyzed folding characteristics, coal controlling faults and sedimentary environment in the area, predicted that coal measures strata possibly still have existed in east of Hushan mining area, Muri coalfield. The structure of predicting area is a broad, gentle syncline, together with Hushan syncline made up a comb fold. Coal-bearing strata belong to Middle-Lower Jurassic Series Jiangcang Formation, coal-forming environment was Mesozoic faulted basin fluviolacustrine, bog facies. The F2 fault is the south boundary fault of the Hushan mining area, it controlled deposition of coal measures strata during early stage, and coal measures buried depth and preservation during later stage. The predicting area is situated at coal measures strata shallower position, in favor of coal seams exploitation and utilization.
