Ma Lisan reinforces along digs the lane coal column to permit the factory coal mine spatially the application

许厂煤矿运用马丽散支护技术对沿空掘巷煤柱进行加固,与传统注浆的加固技术相比,有效地控制了围岩垮落,提供了出面时间和空间,且施工工艺简单,取得了较好的技术经济效益。

Make use of MA3 LI2 SAN3 pays to protect the technique to get empty to dig the lane coal pillar to reinforce towards follow, noting the syrup to reinforce to compare with the tradition to controlled to round the rock to fall availably, provide to appear publicly time and spaces, and start construction the craft is simple, obtaining the economic performance of good technique.
