概率积分法在工业广场煤柱开采技术中的应用

Probability integral square pillar mining in the industrial application of technology

为了增进对工业广场煤柱开采技术的研究,通过覆岩内部移动变形概率积分法理论对回采方案进行科学修正,对回采后主要巷道及硐室的破坏程度、变形量做出了科学的估算,提前进行支护加固。实践证明此方法在工业广场煤柱开采中对于工作面的科学合理布置有重要指导意义,能够有效指导安全生产。

In order to enhance pair of industrial square pillar mining techniques, but through the overlying rock moved within deformation on the extraction probability integral Li Lun Fang An amendment to science, the main gateway to the Hui Cai and chamber after the extent of the damage, deformation provides a scientific estimate, ahead of support reinforcement. Practice has proved that this method in industrial square pillar mining in the face of scientific and reasonable arrangement of important guiding significance to effectively guide the safety in production.
