不同地质单位积累的绳索取心钻进经验表明,在一定的矿山地质条件下使用ССК钻具,可减少提升工序的时间消耗,提高劳动生产效率和改善矿区的取样质量. 功用和结构不同的改型ССК钻具研制成功并且投入生产,在某种程度上满足了具体矿山地质条件的钻进要求.根据钻探技术研究者的意见,如果简化钻具结构,从钻具组成中消
The experience of drilling coring of ropes accumulated in different geologic units shows that the use of ССК drilling tools under certain mine geological conditions can reduce the time consumption of lifting process, improve labor productivity and improve the sampling quality in the mining area. Type ССК drill tool was successfully developed and put into production, to some extent to meet the drilling requirements of the specific geological conditions of the mine.According to the opinion of the drilling technology researcher, if simplify the structure of the drilling tool,
