平庄煤田矿区外围及深部含煤性评价及找煤预测

平庄煤田开采元宝山组煤层已有多年,多个矿井面临资源枯竭局面,寻找后备资源已成为目前亟待解决的问题。通过对矿区含煤地层含煤性评价,认为矿区深部的元宝山组不具有形成可采煤层的条件,其下伏的杏园组沉积晚期为扇三角洲相,扇三角洲平原下部朵叶间湾及湖滨地段为聚煤作用有利场所。根据钻探资料证实,在五家矿区、古山矿区和四龙头矿区杏园组上段均见可采煤层,该组应作为找煤预测区目的层加以勘查。

Coal-bearing Property Assessment and Coal Looking Prediction in Mine Area Periphery and Deep Part,Pingzhuang Coalfield

The mining of coal seams in Yuanbaoshan Formation, Pingzhuang coalfield has been many years, many coalmines are confronted with resources exhaustion, thus to seek supporting resource is an issue demanding prompt solutions. Through evaluation of mine area coal-bearing strata coal-bearing properties, considered that the Yuanbaoshan Formation was ineligible to form mineable coal seams, while the underlying Xingyuan Formation in its late sedimentary stage fan delta facies, fan deltaic plain lower part lobe interdistributary bay and lakeshore sections were locations in favor of coal-accumulating. The drilling data demonstrated that, in Upper Member of Xingyuan Formation in Wujia, Gushan and Silongtou mine areas where mineable coal seams can be seen, so that the formation can be exploration target in coal-looking prediction.
