黄土山区采动损害特征分析及治理

When mining under water, the height of water fractured zone has direct effect on the safety of the production in mines. In this paper, based on the special geological and mining condition in Loess Mountain Areas, analyzes the feasures of mining damage with full mechanized top coal caving mining in thick seam. It has determined the development of water fractured zone, and predicted the possibility of surface water in mining scope inrush coal mine. Some prevebtion and control measures of water disaster have to be taken, which can maintain the coal mine's safety in production.
