Description

Portable drilling device for geographic exploration

Technical Field

The invention relates to the technical field of geographic exploration, in particular to a portable drilling device for geographic exploration.

Background

Geology is one of seven natural sciences, and is mainly used for researching the earth and the cause and evolution development of the earth. The practical application is very extensive: earthquake prediction, search and exploration of various mineral products, disastrous landslide and evolution of ancient creatures. All objects built on the ground have to be known in advance about the underground situation. Geological exploration is investigation and research activities of surveying and detecting geology through various means and methods, determining a proper bearing stratum, determining a foundation type according to the foundation bearing capacity of the bearing stratum and calculating foundation parameters. The method is to find an industrially significant mineral deposit in mineral census, provide mineral reserves and geological data required by mine construction design for finding out the quality and quantity of the mineral and technical conditions of mining and utilization, and carry out investigation and research work on geological conditions such as rocks, strata, structures, mineral products, hydrology, landforms and the like in a certain area.
