In late years a polymer and muddy water are used as circulating material for a high quality core sampling. These are named generally as a core sampling system of construction of high quality including Air Bubble Boring Method. We develop a high quality core sampling system that we can obtain a homogeneous core sample by plural boring machines. And we improve our Air Bubble Boring Method (the Hybrid Boring Method) for a high quality core sampling system. The principal objective of development is improvement of bowling efficiency by reduction of a cut section. In this report, we describe the present conditions of these high dignity core collection methods of construction. We show results of new improvement/development of a HB method of construction and an example in the field.
