平行作业法在岩巷快速掘进中的应用

The Application of Parallel Operation Method in Rapid Excavation of Rock Roadway

为解决岩巷开拓速度慢,正规循环率低,作业繁杂的问题,峰峰集团辛安矿巷修区,大胆尝试,改进生产工艺,逐渐形成了一套科学、有效的"四八交叉平行作业法",推行的"四掘四喷"的新工艺帮助该区在2143设备眼掘进中实现了人工炮掘大规格(4.2m×3.2m,净宽×净高)岩巷平均日进4.3m,最高日进6.3m,27天月进116m的成绩。

In order to solve the problems of low excavation speed of rock roadway, low normal circulation rate, complex operation, the Fengfeng Group Xin’an Mine makes a bold attempt to improve the production process, and form a scientific and effective operation method, it calls＂Eight hours and Four work shifts Parallel Operation Method＂, and promotes the new process of＂Four Excavation and Four Jet＂, and helps the 2143 equipment excavation realizing the achievement of 4.3 m each day in the average, and 6.3 m each day at the maximum, and the total mile of27 days is 116 m, this excavation speed of rock roadway is using the artificial blasting digging, and the rock roadway is 4.2 m wide and 3.2 m high.
