For placer drilling a new method, known as the center sample recovery method, is under development abroad. Drilling is performed by a double-tube rigid type drill pipe driven with a dynamic head. with high pressure air current passing the clearance between the double tube down to the hole bottom and carrying the rock cuttings through the internal pipe up to the earth surface. The specifications of drilling tools, bit types, air current technical parameters, sample collection and division methods,and efficiency for this new placer drilling method are introduced in this paper. It has been also pointed out that this method can not be used for solid mineral sampling and to determine the stratal configuration elements and lithomechnical parameters by direct measurements are impossible.

概括地介绍了国外正在发展的Center sample Recovery钻探法。它是由动力头回转双壁钻杆进行钻进,用高压气流沿管壁间隙通到孔底后,携带岩屑由钻杆中心孔返回地面。介绍了钻具规格性能、钻头种类、气流工艺参数、样品收集与缩分方法,以及这种新方法的高效特点。这种方法不能取得完整岩矿心,从而无法直接测得地层结构要素和岩石的力学参数。
