广西煤炭资源状况及其找煤潜力分析

广西境内早石炭世、晚二叠世以海相成煤为主，早侏罗世、古近纪、新近纪为陆相成煤。煤多属高灰、中-高硫、低热值的“二高一低”煤，已查明的资源总量21.36亿t，保有量18．56亿t。以古近纪-新近纪的煤田最多．其次为晚二叠世煤田。煤类以褐煤、贫煤为主。煤炭资源主要分布于百色-南丹以东、钦州-来宾-柳城-融水以西的区域内。在168个探（矿）区中，仅38％达到勘探程度。根据资源条件及勘查程度，指出在老矿区（井）的外围和深部（如红山矿区西南部、中北部深部、罗城煤田深部、宜山煤田中部、扶绥煤田中段北部、百色煤田中东部）、桂西地区（如凤山-大化、隆林-乐业相对隆起区域、大新古隆起周边）、桂东南和桂南地区（如大洲盆地、钦灵盆地、江平盆地、十万大山盆地）等处有找煤前景，并预测了勘查潜力。

Coal Resources Status and Potential of Looking for Coal in Guangxi

Coal-forming in Guangxi during Early Carboniferous to Late Permian is mainly marine-limnic coal deposits, while from Early Jurassic to Paleogene, Neogene is limnie coal deposits, mainly high ash, medium-high sulfur and low calorific value coal. Identified total resources have 2.136 billion tons, available resources 1.856 billion tons, mainly Paleogene-Neogene coal, next Late Permian coal. Coal rank is mainly lignite and meager coal. Coal resources are mainly distributed to the east of Bose-Nandan line, west of Qinzhou-Laibin-Liueheng-Rongshui line. In 168 exploration （mining） areas, only 38% are explored. According to resource condition and exploration degree, pointed out in peripheral and depths of old mining area （mine） （such as southwestern, middle-north depths of Hongshan mining area, Luocheng coalfield depths, middle Yishan coalfield, north part of middle Fusui coalfield, middleeast part of Bose coalfield）, western Guangxi area （such as Fengshan-Dahua, relatively uplifted area of Longlin-Leye, peripheral Daxin old uplift）, southeastern and southern Guangxi （such as Dazhou, Qinling, Jiangping and Shiwandashan basins） all have looking for coal prospect and predicted exploration potentials.
