正行煤业井下陷落柱特点及预测

Forecast and features of underground collapse column in Zhengxing Coal Industry

针对井下陷落柱较为发育、陷落柱发育大小不一、地质资料不详、无法进行准确的地质分析,给掘进施工带来较大影响的问题,正行煤业有限公司通过对陷落柱发育特点进行科学分析,运用数理统计及运用岩移学理论,预测出陷落柱的范围及陷落柱边界的煤层位置,准确定位钻孔,极大的提高了工作效率。

Based on different sizes of collapse column development, unknown geological data and inacurate geological analysis, there were problems existed in roadway construction. Through scientific analysis of developmental characteristics of collapse column, as well as mathematical statistics and application of rock movement theory, range and boundary seam location of collapse column were predicted to locate borehole accurately, which improved work e^ciency greatly.
