On July 9, the reporter learned from the Henan Geological Survey that the Henan Province bauxite geological project undertaken by the institute has achieved initial results, including the discovery and identification of four large buried bauxite deposits and mineral deposits. The newly discovered bauxite resources amounted to 200 million tons, of which 23.62 million tons were identified. According to reports, the Henan Bauxite Geological Project was jointly deployed by the China Geological Survey Bureau and the Provincial Department of Land and Resources, and the Provincial Geological Survey was the project undertaker. Since 2005, the institute has mobilized a large number of geological experts and related professional and technical personnel to carry out the work, so that the province's bauxite prospecting and exploration work has been rapidly advanced, and has achieved a number of major achievements.

On the basis of practice, Henan Province proposed a sedimentary bauxite metallogenic model in North China, successfully predicted the potential of bauxite resources in Henan Province, in bauxite metallogenic theory, prospecting methods, prospecting results and mineralization. Major breakthroughs have been made in forecasting and other aspects.Chisel
Chisels are classified in different shapes according to different uses:
Flat chisel: the cutting edge is flat, the cutting edge and the chisel body is an inverted isosceles triangle, mainly used for opening square holes or repairing some square holes;
Oblique chisel: the blade is 45° Angle, the blade and chisel body is an inverted right triangle, mainly used for repair, most of the dead corners for carving and carving repair;
Gouge: the cutting edge is semicircular, mainly used for opening circular or elliptical holes;
