综放工作面的两条回采巷道为全煤巷,断面面积大,围岩强度低,采用锚杆支护能较好控制巷道的变形,锚杆支护设计关系到巷道锚杆支护工程的质量优劣、是否安全可靠以及经济是否合理,利用压力拱理论为基础,对回采巷道锚杆支护的各项参数进行科学设计,设计方案在某矿中实际应用效果来看,能够保证顶板的稳定,巷道在使用期限内的变形量满足回采工作要求,整体维护效果良好。
綜放工作麵的兩條迴採巷道為全煤巷,斷麵麵積大,圍巖彊度低,採用錨桿支護能較好控製巷道的變形,錨桿支護設計關繫到巷道錨桿支護工程的質量優劣、是否安全可靠以及經濟是否閤理,利用壓力拱理論為基礎,對迴採巷道錨桿支護的各項參數進行科學設計,設計方案在某礦中實際應用效果來看,能夠保證頂闆的穩定,巷道在使用期限內的變形量滿足迴採工作要求,整體維護效果良好。

The two lane roadways for working face are formed by coal, the cross-sectional area of which is large and the rock strength of which is low, so using bolting to control the deformation of roadway is better. Bolting design is related to the quality of rock bolting engineering and to whether it is safe and reliable and is economical. Under the pressure arch theory,every parameter of roadway bolting is designed scientifically. In the practical application of the design to a mine, it is able to guarantee the stability of the roof, and the deformation of roadway in the period of use meets the requirements of the recovery work, and overall maintain is in good effect.
