摘要
由于传统的煤巷围岩支护形式和理念严重制约着锚杆支护技术在焦作矿区煤巷的推广,因此,首先根据焦作矿区煤巷生产地质条件,采用模糊聚类法建立矿区煤巷围岩稳定性分类,即分为中等稳定的Ⅰ类和不稳定的Ⅱ类,然后分析了中等稳定煤巷(松软顶板煤巷)和不稳定煤巷(高应力松软顶板煤巷)这两大类煤巷的围岩变形特征及控制技术,并确定了各类煤巷的较优支护形式和参数。
Due to the traditional supporting patterns and concept of roadway surrounding rock restrict the promotion of bolting technology in Jiaozuo coal lane,this paper adopted fuzzy clustering method to establish the stability classification of roadway surrounding rock under the geological conditions of production.The stability classification is divided into mid-stable class Ⅰ and unstable class Ⅱ,then the paper analyzed the rock deformation and control technology of roadway surrounding rock between mid-stable class and unstable class,identified the better support form and parameters in various types of roadway.
