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。
The mining of the Yuanbaoshan coal seam has been carried out in Pingzhuang coalfield for many years and many mines are facing depletion of resources. Looking for reserve resources has become an issue to be solved urgently. Based on the evaluation of the coal-bearing property of the coal-bearing strata in the mining area, it is considered that the deep ingot of the Yuanbaoshan Formation does not have the conditions for the formation of a recoverable coal seam. The lower Apricot-Orbital Sedimentary facies is the fan-delta phase and the lower part of the fan delta plain And lakeside lots of coal for a favorable place. According to the drilling data, it is confirmed that recoverable coal seams are found in the upper reaches of the five mining areas, the Gushan mining area and the Xinglong group in the Four Lengtou mining area, and the group should be surveyed as a target prospecting coal prospecting area.
