巷道围岩位移量是评价巷道稳定性的重要指标,也是巷道布置、采区设计、支护形式选择的重要依据。开滦矿区几个老矿井开采深度达700～1000m以下,巷道地压大、变形严重、支护困难,因此,巷道位移量计算在生产中日益重要。我们在开滦矿区巷道现场实测的基础上,经过数理 Roadway surrounding rock displacement is an important indicator to evaluate roadway stability, but also an important basis for roadway layout, mining area design and support form selection. The mining depth of several old mines in Kailuan Mining Area is below 700 ~ 1000m, the ground pressure of the roadway is large, the deformation is serious and the support is difficult. Therefore, the calculation of roadway displacement is increasingly important in the production. Based on the field measurements of roadway in Kailuan Mining Area, we went through mathematical calculations
