在砂矿钻探中，为避免流水对砂样的冲刷、分选溶蚀，一般均不使用冲洗液钻进，同时因其孔浅，施工周期短，所以必须尽量简化设备，缩短拆、迁安时间，为此我们在尽量利用已有设备材料的基础上，使用XJ-100型钻机去掉立轴及水泵，加强离合器与卷扬机制带的强度；动力改用风冷式195型12马力柴油机，这样既减轻了设备重量又免除了经常添加柴油机冷却水的麻烦。利用φ73岩心管制作6.5m“A”型简
In sand mine drilling, in order to avoid running water on the sand sample erosion, separation and erosion, generally do not use the drilling fluid drilling at the same time because of its shallow hole, the construction period is short, so we must try to simplify the equipment, shorten demolition, Qian’an time , So we make full use of existing equipment, based on the use of XJ-100-type drilling rig to remove the vertical shaft and pump to enhance the strength of the clutch and hoist belt; power switch to air-cooled 195-horsepower diesel engine 195, so that both reduce The weight of the device eliminates the need for frequent addition of diesel engine cooling water. Using φ73 core tube 6.5m “A” type Jane
