Abstract
Taking the 051508 comprehensive transportation tunnel of Shanxi Changzhi Huashengrong coal mine as the engineering background, based on field investigation, the paper comes to the conclusion that the original supporting scheme is unreasonable, and roadway support is not effective. Based on the geological conditions of the working face of the comprehensive transportation tunnel, a simplified mechanical model is established, and the actual suspended ceiling distance between the upper and lower two sides of the roof is calculated. The analysis shows that the roof rock failure has asymmetric distribution characteristics. Based on this, it is concluded that the most reasonable and economical support scheme is optimized under the premise of safety, high yield and high efficiency, which provides an important reference for similar conditions to support the roadway with large section.关键词
