mine engineering
2.We discussed the main characteristic parameters of seismic kinesiology and dynamics of mine engineering fracture zone, including relative amplitude, phase time of wave crest, similarity factor, principal frequency band energy, 3-D space time gradient and coherent coefficient et al., and puts forward the processing method of 3-D seismic characteristic parameters about denoise-smoothing, generalization, correlation analysis, characteristic transformation; and presents the method of pattern recognition of mine engineering fracture zone.
3.The acticle passes the actual working experience of drilling bole explore for open coal mine engineering geology explain simbly a few problems of the dumping site leave thing layer meet with drilling hole explore, probe detailed the treatise and the technique meathod to. solve these problems.
5.This paper discusses the feasibility of the mine restore engineering from the aspects of mine field exploit, aeration, lift, ground production system.
6.The filling pile drilling machine of KP2000 type applies to pore forming construction of various architectural base and shallow well with heavy caliber, vertical well of small coal mine, defense engineering bore using and other drilling projects.
7.In this paper environment risk assessment of the mine tailings reservoir engineering making use of open pit abandoned at Paishanlou Gold Mine was carried out.
8.The practical application of hollow steel ball, solid bolt ball and mine bolt ball to architectural engineering is introduced in this article.
9.Theories and methods of safety science and technology; Industry safety (mine, petroleum, chemical industry and engineering, ordnance, aeronautics and astronautics, civil engineering, transportation, navigation, nuclear industry et al); Risk assessment and analysis; Major hazardous sources identification, managemant and control; Safety management, safety education and safety training; Prevention of fire, explosion, dust and corrosion .
