摘 要:对位于松散破碎围岩中巷道支架受力作较详细分析,指出了在成巷初期及后期由于压力拱的动态发展变化而导致支架受力的不同,在理论上提出支架受力近似计算式,通过实例应用表明分析结果与实际情况相符。ased on the detailed analysis of roadway support in loose and broken surrounding rock, it was pointed that the dynamical development of pressure arch causes the different support load at earlier stage and later stage of roadway excavated. Theoretically,a proximate formula for calculating support load was established. Practical usage indicated that the analytical results tally with the facts well.
