自五十年代以来,我国在矿山巷道支架设计与使用中长期采用普罗托奇耶柯诺夫的压力拱理论。从理论上的假设到井巷使用中出现的大量事故,我们感到普氏地压理论存在不少问题。根据普氏地压理论的计算,有的拱壁过厚,造成浪费;有的拱壁不安全,产生裂隙,甚至坍塌。为此,本文提出一个修正公式,供讨论。 由普氏地压标准公式的推导过程得知: Since the 1950s, Protondyyeonov’s stress arch theory has been adopted in the design and use of mine roadway supports in our country. From the theoretical assumptions to the large number of accidents in the use of shafts, we feel there are many problems with Plattski pressure theory. According to Platts theory calculations, some arch walls are too thick, resulting in waste; some arch walls are not safe, cracks, or even collapse. To this end, this article proposes a correction formula for discussion. By Platts formula to deduce the standard process of derivation:
