摘要
通过对辛置井田陷落柱的特征进行分析,寻找其在井田内的分布情况,并通过对2号与10号煤层内陷落柱的中心轴的分析,找出其上下位置关系,从而为下组煤的开采提供技术依据。
On the analysis of development characteristics of collapse columns in Xinzhi coal field,their distribution was determined. The relation between upper and lower position were found out by the analysis on central shaft of the collapse columns in No.2 and No.10 coal seam, which could provide technical support for the mining of the lower group coal.
