大断面硐室支护技术研究

Study on Large Section Chamber Support Technology

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。因为此处巷道为胶带巷,巷道断面突然增大会对井下生产造成很多不利影响,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。

Yangquan Mining Group No. 1 Mine S3 mining area downhill belt machine head chamber roadway with height3.5 m, width 6.5 m, due to roadway influenced seriously by ground stress, high caving in some area, the highest point in the roadway is 7 m. Because the roadway is belt roadway, the sudden increase of roadway section may cause negative influence for underground production, based on the geological mining condition of the roadway, anchor nets support technology was adopted, with good support effect.
