结合1303工作面地质条件及生产技术条件,分析了影响本工作面冲击矿压的主要因素,进行了冲击矿压危险区域划分。制定了回采前进行大直径钻孔卸压预处理、回采期间采取大直径钻孔卸压及煤体爆破等工作面防冲措施,同时加强支护。现场实践效果良好,保证了安全回采。
結閤1303工作麵地質條件及生產技術條件,分析瞭影響本工作麵遲擊礦壓的主要因素,進行瞭遲擊礦壓危險區域劃分。製定瞭迴採前進行大直徑鑽孔卸壓預處理、迴採期間採取大直徑鑽孔卸壓及煤體爆破等工作麵防遲措施,同時加彊支護。現場實踐效果良好,保證瞭安全迴採。

Combined with the geological and production conditions of No.1303 working face, the main factors influencing rock burst at working face were analyzed,and the rock burst danger-ous regions were divided.The preventive rock burst measures at working face were determined, including pressure release via large diameter boreholes before and during mining as well as coal blasting.Combined with reinforced supporting and above measures,the safe mining was guaran-teed.
