摘要
煤矿综采工作面厚硬砂岩顶板对采煤工作面影响极大,如果处理技术不合理,将造成严重的安全事故。为此经过多年的理论分析和工程类比,提出了一套较为完善的顶板深孔爆破强制放顶参数,在工程实践中应用,取得了良好的经济和社会效益。
The thick and hard sandstone roof of the fullymechanized coal mining face has great influence on the coalmining face. If the treatment technology is unreasonable, it willcause serious safety accidents. After years of theoretical analysisand engineering analogy, a set of more perfect parameters forforced roof caving of roof deep hole blasting is put forward, andgood economic and social benefits have been obtained inengineering practice.
