Overview
ABSTRACT
Drilling and coring are the main techniques for the exploitation, exploration and observation of soils. The principle of drilling consists in finding and exploiting underground natural resources (water, oil, gas, mineral resources) or carry out geotechnical actions. The technical means implemented (equipment, workforce, etc.) vary according to the objectives and size of the project. Coring, however, consists in collecting a sample in the ground by means of a tube. The core collected provides information on the geological activity of the soil, via its stratigraphic study. This article presents the two methods, detailing the processes, materials and equipment, and the parameters to be studied and taken into account.

INTRODUCTION
Since time immemorial, man has sought the materials necessary for survival and development in the subsoil.
To do this, he developed increasingly sophisticated techniques and equipment. But it was undoubtedly the traversing, or sampling, of rocks that posed the greatest number of problems.
This article focuses on the various drilling and coring methods used in steep soils and rocks, and the equipment they use.
