大断面硐室支护技术研究

Study on support technology of large cross-section chamber

阳煤一矿S3采区下山胶带机头硐室巷道高3.5 m、宽6.5 m,由于巷道受地应力影响严重,部分区域高冒,巷道最高处达到7 m。针对该处巷道的地质采矿条件,采用锚网支护技术对该处巷道进行支护,支护效果良好。

Affected by ground stress, the deformation of the belt conveyor head chamber of $3 mining area dip of YangMei NO. 1 with high 3.5m, wide 6.5m,is seriously, the highest part of roadway reaches 7m, the sudden increasing of the roadway section will cause a lot of adverse effects on underground production, according to the geological and mining conditions of the roadway, used the bolt-net support technology, gotten the good supporting effect.
