西山煤田西铭井田陷落柱规律及未采区预测

Laws of Collapse Columns and Prediction of Non-mining Areas Ximing Well Field of Xishan Coal Field

综合多年收集的原始资料 ,总结出各煤层所见陷落柱柱体岩性、大小、大致冒落距 ,以及柱体的压实、胶结程度和柱体内常见的矿物结晶 ,并对采煤顶板管理进行了分析。研究了整个矿区内陷落柱的分布规律 。

Original data of the past many years are analyzed and synthesized,the rock nature,size and rough distance of roof fall,compressed and cemented degree,common mineral crystal of the discovered collapse columns in each coal layer are summed up,and roof management is discussed. In addition,the distributing laws of collapse columns in whole mine area,are also studied,the drawn conclusions are applied to the prediction of the collapse columns in non-mining areas.
