Application Research Of Drilling Advanced Water Exploration Technology In The Excavation Of A Mine Roadway

With increasing depth of mining and hydrogeological conditions becoming more complex, water brusting is more seriously. It is difficult to proved the geological condition of the complex coal mine just rely on a single means of geological exploration. Although it could get obvious results by traditional technology method such as drilling or lane appeared, but it is hard to make macroscopic detection under mine of complex geology. However, the geophysical exploration technology has made up for the shortages, drilling advanced exploring water technology is a kind of integrated geophysical prospecting which based on resistivity method and induced polarization method. The systematic research aims at the application of drilling advanced exploring water technology applying in excavation roadway, the following several aspects of research results have been obtain:1, Verify the advantages of resistivity method and induced polarization method via the resistivity characteristics of surrounding rock, the induced polarization properties, dielectric properties, magnetic, and other physical properties analysis.Combined with the value assignment method, borehole ground water technology theory of detection range in advance has been proved.2, In view of the positive and diagonal directions, the experiment distinguishes detection effects, recognitions and influence factors of different directions by the pond simulation. Further validation of borehole ground water technology in the actual detection range in advance has been made.3, Selected TaiFeng weng 'an coal mine's 1106 return air trough in excavation roadway as a experimental unit for the engineering practice, the effective of detection of 1 #, 2 #, 3 # has been made by YZT6 drilling advanced detectors respectively. The result shows that a radius of 30m' crack trouble area which is centered at A?B and a connected geological anomalies which is centered by C are exist. According to the result, it caused by gob.4, The experiments verified the 1106 return air trough in excavation roadway by TEM which reconnaissance it from the roof direction, the tunneling direction and the floor direction respectively. The results show that there are 3 #, 5 #, 7 # connect low resistance of geological anomalies, what is the same of exploration results by advanced drilling technology.So it proved that the method is feasible.
