近几年随着绳钻技术的推广应用,建材系统不少单位,应用绳钻施工斜孔、水平孔也取得了良好的技术经济效果。如广东建材地质队在英德龙尾山石灰岩矿区,应用YS46绳钻施工深190~230m、75°斜孔7个,完成工作量1514.29m,平均台月效率847m,平均矿心采取率95%。陕西建材地质队在洋县大岭梁石灰岩矿区,应用SC56绳钻施工深236~326m、45°斜孔5个,完成工作量1437.79m,平均台月效率655.2m,最高971.3m,平均岩矿心采取率92%以上。四川建材地质公司,在四川石棉矿尖石包1539中
In recent years, with the promotion and application of rope drilling technology, building materials system, many units, the application of rope drilling oblique hole, horizontal hole also achieved good technical and economic results. For example, Guangdong Building Materials Geological Team used the YS46 rope drill to construct deep 190 ~ 230m and 75 ° inclined holes in the Anglo-German Longwei Mountain limestone mining area. The completion workload was 1514.29m, the average monthly efficiency was 847m, and the average mining rate was 95%. Shaanxi Geological Team building materials in the Yangling Dalingliang limestone mining area, the application of SC56 rope drilling deep 236 ~ 326m, 45 ° inclined hole 5, the completion of the workload of 1437.79m, the average efficiency of 655.2m per meter, the highest 971.3m, the average rock and mine Heart rate of 92% or more.
