重新支护支架已经变形的主要巷道,是矿山最困难的工程之一。它不易实现机械化,费用昂贵。本文介绍某矿山修复巷道支架的经验。该矿矿体位于约500米深的含水粘土质砂岩中,由于岩石非均质,即使在疏干后,许多区段中地下水的剩余压力仍有0.01～0.1兆帕。这些区段的位置实际上不可能预测,因此支架的选择有时是不理想的。恰在这些区段支架发生变形和破坏,必须进行修理。 Re-support the main deformation of the roadway has been the mine is one of the most difficult projects. It is not easy mechanization, expensive. This article describes the experience of a mine repair tunnel support. The ore body, located in an aquifer clay with a depth of about 500 meters, still has a residual pressure of 0.01 to 0.1 megapascals in many sections due to rock heterogeneity even after dredging. The location of these sections is virtually impossible to predict, so the choice of bracket is sometimes not ideal. Just in these sections stent deformation and destruction, must be repaired.
