Study on Fully-Mechanized Top Coal Caving Mining under Water Body with Shallow Overburden and Thin Bedrock

Lei Li, Zhi Guo Liu, Pei Pei Chen, Gui Liu

Abstract

Based on the geological condition of MaHuangliang coal in the Yushen mining area, the paper systematically studied the overburden's destructiverules of fully-mechanized top coal caving, and established hydro-geological model of research area by using GMS numerical simulation. Based on the model, the paper predicted the water inflow of different aquifer, analyzed the influence of aquifer to coal mining, and introduced the technical plans about fully-mechanized top coal caving mining under water body with shallow overburden and thin bedrock.
