摘　　要：因地层结构问题,钻孔施工不能顺利进行,严重影响矿井正常施工进度和质量,成本增加。假如在矿山地质资源勘查中攻克不下钻探技术难题,该钻孔施工将不能如期完工。为此,结合施工中发现的问题,剖析、研讨,采取有效合理的钻探技术方法,以解决钻孔施工中的难题。Because of the stratum structure problem, the drilling construction can not proceed smoothly, which seriously affects the normal construction progress and quality of the mine, and increases the cost. If the technical problems of drilling can not be overcome in the exploration of mine geological resources, the drilling construction will not be completed as scheduled. Therefore, combined with the problems found in the construction, analysis and discussion are carried out, and effective and reasonable drilling techniques are adopted to solve the difficult problems in drilling construction.
