摘要
陷落柱是影响采煤工作面正常开采的较大因素,官地矿通过用中深孔爆破技术破坏原有的陷落柱结构,极大地提高了工作面回采效率,优化了施工工艺,降低了职工的劳动强度,保护了综采设备,提高了矿山生产效率,值得在包含有陷落柱的工作面进行推广使用。
Collapse column is a big factor affecting the normal mining of coal mining face.Guandi Coal Mine destroyed the original collapse column structure by using medium deep hole blasting technology,which greatly improved the mining efficiency of working face,optimized the construction technology,reduced the labor intensity of workers,protected the fully mechanized mining equipment,and improved the production efficiency of the mine.It is worth promoting in the working face with collapse column use.
