动压区大断面煤巷锚杆支护设计

Design of bolting support used in large cross-sectional coal drifts in dynamic pressure zones

介绍了冀中能源金牛股份公司东庞矿在动压作用期内沿空掘巷矿压分布规律及支护技术的实践与应用。通过采用相似材料模拟研究和数值模拟计算,确定了锚梁网加锚索联合支护设计,同时进行了矿压观测,取得了较好的支护效果。

This paper provides a presentation about the mine pressure distribution pattern in gob-side entry driving within the dynamic pressure period and the practical use of support technology in Dongpang Coal Mine, Hebei Jinniu Energy Co Ltd. Similar materials and similar data are used in the simulation research and simulation calculations. In this way, a combined support design composed of bar and wire mesh and bolting cables is determined which is followed by tests under mine pressure conditions; The tests produce good results of the supports.
