Absrtact: With the rapid development of China's economy, the demand for resources is increasing, mineral enterprises have emerged in large numbers, and the number of mining construction projects has increased significantly. There are some special chambers in mining construction projects, which have relatively special functions and play an extremely important role in mining construction projects, therefore, their support work is very important. This paper focused on the soft rock support technology of special chambers in mine construction projects, during this period, first analyzed the status quo and problems of special chamber soft rock support in mine construction projects in China, and then explored the special chamber soft rock structure support method, finally gave an example for analysis in order to provide theoretical support for the construction unit, design unit and mining unit of the mine construction project.

在矿建工程的施工过程中,部分特殊硐室处于软岩环境,通常具有特殊功能,一旦修建完成,大多数无法进行反复维修,建设之初就必须保障其质量。在对特殊硐室进行设计和施工的过程中,人们必须深入分析硐室所处软岩环境的结构可塑性、膨胀性等,采取合理的支护技术,制定科学的支护方案,确保支护施工达到预期效果,使软岩环境的结构保持相对稳定的状态,特殊硐室安全稳定。
1 我国矿建工程中特殊硐室软岩支护现状
随着我国科学技术的不断发展,很多先进的矿产开采技术得到广泛的运用,极大地提高了矿产企业开采的安全性和稳定性。目前,在我国矿建工程中,特殊硐室软岩支护技术仍有较大的提升空间,传统的软岩结构硐室支护技术已经无法满足实际施工需求,以至于安全事故频发,严重影响矿产企业的开采效率和施工人员的人身安全。……
