引言众所周知、未经掘进或回采工作破坏的岩层,其任何一处的岩石都受到上、下、左、右、前、后岩石的挤压,而上下、左右、前后挤压力的和等于零。但在岩层中开掘巷道时,情况就发生了变化。为了使巷道保持一定的断面形状和大小,就需要阻止巷道围岩发生变形和破坏,即需要进行支护。倾斜巷道施工中,除对平巷掘进施工所注意的事项外,还要对巷道的倾角、支架的迎山角、棚腿扎角加以注意。要想安全、快速、省材的搞好上山掘进,除理论
INTRODUCTION Rocks that are known to have been destroyed by excavation or mining work are rocked at any point by upper, lower, left, right, front, and back rocks, and the sum of the upper, lower, left, and right front and rear extrusion forces is equal to zero. However, when the roadway was digging in the rock formation, the situation changed. In order to maintain a certain cross-sectional shape and size of the roadway, it is necessary to prevent deformation and destruction of roadway surrounding rock, that is, support is needed. In the construction of the inclined roadway, besides paying attention to the matters concerning the construction of roadway excavation, attention must be paid to the inclination of the roadway, the angle of support of the mountain, and the angle of the shed leg. To safely, quickly, and materially improve the excavation of the mountain, in addition to theory
