厚煤层大断面回采巷道围岩控制技术研究

摘要

本文针对厚煤层大断面回采巷道围岩控制难题，结合现场实际地质及生产技术条件，采用工程类比方法确定锚网索带联合支护形式，采用悬吊理论进行参数验算，并通过支护工艺要求保证工程质量。现场实践取得良好的经济技术效果。%For the surrounding rock control problem of the roadway with large section in thick coal seam, combined with the actual geological and technical conditions of production, using engineering analogy method determined anchor-net-cable combined support form, using the suspension theory to check, and ensuring the engineering quality by the support technology requirement, which achieve good economic and technical results in field practice.
