摘要:随着经济的发展和社会的进步,人类社会所消耗的矿产资源越来越多,为了缓解资源短缺,向地表更深处开采矿产是一种有效的措施。深层地表矿产的勘探开发对钻探技术提出了更高的要求,随着钻孔的不断加深,钻孔内部也变得更加复杂,施工难度也越来越大,而岩心钻探水泥注浆护壁技术更加显示出它的重要作用。文章首先全面的分析了岩心钻探遇到的问题,接着深入探讨了钻探水泥注浆护壁技术,最后文章还提出了相应的防塌措施,希望能够引起人们对这一研究的进一步关注,能够对实践起到一定的指导作用。

Abstract: with the development of economy and the progress of the society, the human society the consumption of mineral resources is more and more, to alleviate the shortage of resources to the surface deeper mining mineral is a kind of effective measures. Deep surface to the exploration and development of mineral of drilling technology put forward higher request, with the deepening of drilling, drilling interior also become more complicated, difficult construction also more and more large, and core drilling cement grouting technology more applied shows its important role. This article first a comprehensive analysis of the core drilling problems, then discuss the drilling cement slurry-supported grouting technology, finally the paper also puts forward corresponding measures to prevent the collapse, the hope can cause people to the further attention, can play a role in guiding the practice.
Keywords: core drilling, rinses, cement grouting, the slurry-supported collapse

一、引言
随着经济的发展和社会的进步,人类社会所消耗的矿产资源越来越多,尽管我国倡导构建资源节约型、环境友好型社会,然而,人与自然资源的矛盾仍然比较突出,很多矿产资源因为过度开发,几乎将要濒临枯竭。为了保障经济社会的可持续发展,有必要向地表深处进行矿产资源开发,这就对钻探技术提出了更高的要求。为了保证钻探施工的顺利进行,钻探技术不仅要能够满足在复杂地层进行施工的要求,同时还要做好岩心钻探泥浆护壁防塌工作。
二、岩心钻探存在的问题
岩心钻探是一种常用于固体矿产地质勘探的手段,他在矿物的勘探、开发中起着重要的作用。对于复杂地表的深孔钻探而言,岩心钻探存在着一些问题与不足,总的来说包括以下几点。……
