“洛阳铲”钻探实质上是在第四系复盖层及其下部基岩风化壳中进行人工冲击钻探的一种方法。1971年,针对施工地区普遍为第四系浮土复盖的特点,我队在低品位可选磷灰石矿地表评价工作中,应用“洛阳铲”钻探取得了一定效果。次年,在某大型膨润土矿勘探过程中,应用“洛阳铲”钻探又获得了显著成效。现已在全队各矿区推广应用。一“洛阳铲”钻探在地质普查中的应用 1.代替大部分槽探用来进行大比例尺地质填图工作。在矿产普查评价工作中,每个矿区都不同程度的被第四系浮土复盖着,尤其是第四系广布的薄层复盖区(如某大型膨润土矿,浮土复盖面积约占90％以上)均可用“洛阳铲”钻探代替绝大部分楷探和人工剥土进行大比例尺地质境图工作。据地质图比例尺大小与要求,按一定间距的线和点布 “Luoyang shovel” drilling is essentially a method of artificial impact drilling in Quaternary overburden and its underlying bedrock weathering crust. In 1971, in view of the general characteristics of the covered area in the Quaternary in the construction area, the team made some achievements in the appraisal of low grade alternative apatite surface land using “Luoyang Shovel” drilling. The following year, in a large bentonite ore exploration process, the application of “Luoyang shovel” drilling has achieved remarkable results. Now the team to promote the application of the mine. A “Luoyang shovel” drilling in the geological survey 1. Replacement for most of the trench exploration used to carry out large-scale geological mapping work. In mineral prospecting and evaluation work, each mine area is covered with Quaternary sediments to varying degrees, especially the widely distributed thin layer covered area of ​​Quaternary (for example, a large-scale bentonite mine covers an area of ​​about 90% %) Can be used “Luoyang shovel” drilling instead of the vast majority of Kai and artificial stripping of large-scale geological map work. According to the geological map scale size and requirements, according to a certain distance of the line and point cloth
