| 摘 要： | 对各种岩性的山体进行削坡减载是矿山地质环境治理项目中的重要工程。以江苏省某地矿山环境治理项目为例，对高边坡坚硬石体削坡的“露岩爆破法”、“膨胀剂破碎法”、“二氧化碳致裂法”、“机械破碎法”4种方法进行了比较和优化，在分析了该工程的施工重点、难点的基础上，选用“二氧化碳致裂法”施工，取得了良好的效果。详细介绍了工程的施工工艺、施工过程等，总结了相关经验，对用“二氧化碳致裂法”施工进行了进一步的思考。

| Abstract: | Slope-cutting and load-reducing for mountain bodies of various lithologies is an important job in the mine geological environment control project. Taking a mine environmental control project in Jiangsu Province as an example, comparison and optimization is made of four methods: open rock blasting method, expanding agent crushing method, carbon dioxide fracturing method, and mechanical crushing method for cutting hard rock on high slopes. Based on the analysis of the key points and difficulties on the project, carbon dioxide cracking was selected. This paper introduces the construction technology and process of the project in detail, summarizes the relevant experience, and presents further thought on the carbon dioxide cracking method. |
