The Appliance Research Of High-Density Resis Tivity Method On Deitcting Colliery Underground Gob

High-density Resistivity Method, brought forward by Johansson doctor(American) in 1970s, is a new electric method technology used broadly. With quantity of gathering data increasing and reversal software perfecting, interpreting precision to exploring underground geologic substance is improved incessantly.Coal mine gob is one of the main reason that result to geologic disaster. It not only brings on geologic environment deteriorating, ground sinking, building inclining and cracking, infield destroying, ground seeper, entironment havocing and so on, moreover, it badly affects sustained economic development and social stabilization.Firstly, the paper discusses the connection between different kind of underground gob from excavating coal of different manner and terra electricity speciality. It thinks that colliery gob of high extent mechanization destroys its overcast terrane badly, the amount of crack is excessive and the acreage of sinkage is large. The characteristic of terra electricity is high parallactic resistivity value, large-scale distributing, obvious law and facile...
