摘 要:
采深近千米的矿井地应力大，尤其回采巷道受多种作用力的影响，巷道变形严重。通过采用高强度锚杆锚网梁组合支护技术，在高强度锚杆支护系统的基础上，进一步在顶板和两帮增加锚索加强支护，有效地改善了巷道使用状况，强化了围岩的相对稳定。[著者文摘]

Wall Rock Control Technology of Coal Roadway in Deep Mine
MENG Ya-ping XIE Guo- qiang （ Hebei Jinniu Energy Co. , Ltd, Hebei Xingtai 054000）
Abstract:
The mine in depth of nearly 1,000 meters has very strong ground stress, particularly the mining roadway, which is severely deformed due to the impact of a variety of forces. Through the use of high - intensity anchors and beams of network bolt supporting technology, based on the high - intensity bolting system further adding the anchor cables to the roof and the two ribs to strengthen the supporting, thus improving effectively the use of roadway, and enhancing the relative stability of the wall rock.[著者文摘]
Key words:
