孤岛煤柱工作面回采设计及施工安全探讨

The Design of Isolated Pillar Mining and the Safety Construction

矿井在生产过程中,特别是衰老矿井都存在孤岛煤柱现象,如何能够安全回收该煤柱,以提高矿井采出量延长矿井寿命,成为矿井生产的难题,本文就回收孤岛煤柱的设计方法及施工期间的安全进行探讨。

In the mine production process, especially in the aging coal mine, isolated pillar phenomenon is common. How to draw a safe recovery of the coal pillar so as to improve the production of the mine and prolong the mine life has become a mine production problem. This paper discusses the isolated pillar mining method and the safety during the period of the construction.
