摘要
根据姚楼井田地质勘探所取得的资料，分析了Ｂ煤开采上覆岩土层的水文地质结构及工程地质特征，对该井田厚松散层含水层下近露头带开采的防水煤岩柱尺寸作出了评价，为开采设计提供了初步依据。
On basis of data from geological prospecting,the hydrogeological structure and engineering geological characteristics of overburden rock and soil formation above mining coal B in Yaolou mine are analysized.The size of previous remaining coal rocl pillar preventing water,mining near outcrop belt under soft thickness aquifer,are evaluated.It provides preliminary basis for the mining coal plan.
