摘要
在井巷支护技术的研究中,如何确定岩石巷道二向压力方向及量值是解决支护问题的关键之一。从实测、理论、地质三个方面着重研究了利用巷道断面变形系数估算巷道上大小压力量值的方法,可用于岩石巷道断面上二向压力的近似计算,其方法简单,计算方便,适用于二次支护施工要求,具有工程实用价值。
In the study of support technology in the development of mine ,the key point is how to determine the direction and value of two-dimentional stress of working section. This paper mainly introduces a method to estimate the stress in the working section through displacement coefficient of working section through the three side of spot measure,theory,geology. This method can be used to calculate approximately the vertical and horizontal stress of working sections in the development of roadway .
