分析了掘进巷道断面形式的影响因素,阐述了地质预报和井下实际的地质构造对煤矿巷道掘进中断面优化的作用;提出适合特殊地质条件下,掘进巷道合理断面形式、断面设计参数及正确的井巷支护;从而可以有效的控制巷道围岩变形,预防煤矿巷道掘进中的冒顶事故。
This paper analyzes the influencing factors of cross-section of tunneling roadway, expounds the effect of geological forecasting and actual underground geological structure on tunneling section optimization of coal mine roadway, and puts forward some measures to optimize tunneling section’s proper section, section design parameters and correct well under special geological conditions Laneway support, which can effectively control the deformation of roadway surrounding rock and prevent coal mine roadway heading accident.
