中国矿业大学与潞安王庄矿协作,针对王庄矿3~#煤层顶煤厚度大、综放开采和沿空窄煤柱护巷等特点开展锚杆支护技术研究,取得了成功,在总体上达到国际先进水平。研究中提出锚杆支护围岩强度强化理论和综放沿空巷掘巷大、小结构稳定性原理,并成功应用于该矿6108综放工作面沿空掘巷的锚
China University of Mining and Luan Wangzhuang mine collaboration, in view of Wangzhuang 3 ~ # seam thickness of coal, fully mechanized top coal caving and narrow gobbling lanes and other characteristics of the anchor bolt support technology has been successful in the Overall reached the international advanced level. In the research, the theory of strengthening strength of surrounding rock with bolt support and the principle of large and small structural stability of gob-side entry of gob-side entry of fully mechanized top-coal caving are put forward and successfully applied to anchor of gob-side entry in 6108 fully mechanized caving mining face
