摘　　要：小回沟煤业进入副斜井井底西辅运大巷工程施工交岔点工程时,由于遇到大断面、软岩和破碎带等较为困难的施工地质条件,采取了以锚网喷支护技术为基础,组合U型钢支架加强支护的方式,积极、主动、有效地控制了围岩巷道变形,阻止了巷道的变形恶化,显著提高了巷道围岩的强度及其承载能力,降低了工人劳动强度,成功实现了安全、快速掘进,取得了较好的安全效益和经济效益。When Xiaohuigou Coal Industry Co.,Ltd.carried out the intersection engineering in the west auxiliary transportation roadway project in the sub-inclined shaft bottom,due to the difficult construction geological conditions such as large cross-section,soft rock and fracture zone,it adopted the anchor mesh cable spray support technology combined with U-shaped steel supports as strengthening support,which actively and effectively controlled the deformation of the surrounding rock of roadways,prevented the deformation and deterioration of the roadway,significantly improved the strength and bearing capacity of the surrounding rock of the roadway,reduced the labor intensity of the workers,and successfully achieved safe and fast tunneling,achieving good safety and economic benefits.
