摘要
鲍店煤矿主立井箕斗装载硐室总高度20.49m,掘宽8.5m,掘进工程量1337.9m3。箕斗装载硐室安排与主井井塔平行施工,节省矿井建设工期3个月。硐室锚喷和钢筋混凝土分两次支护,让围岩得以变形,充分发挥了围岩自身的支撑能力,使第二次衬砌的钢筋混凝土碹得到一个较大的承载力安全系数。
The total height of main shaft skip loading chamber in Baodian coal mine is 20.49m, and the excavation width 8. 5m, tunneling 1337. 9m^3. The parallel construction arrangement of skip loading chamber and main shaft tower saved 3 months for mine construction time. Chamber of bolt - shotcreting and reinforced concrete support were applied in twice, letting the surrounding rock deform, to give full play to the support ability of surrounding rock, endowing the second lining of reinforced concrete arch with a larger load safety factor.
