The experiment technique study is important for acquiring accurate data in seismic exploration for metal deposits. The authors obtain the epoxy mixed material with the velocity differences from 1 600 m/s to 3 200 m/s by controlling weight ratio, which can satisfy modeling different kinds of rock, structure and deposit. The authors develop a cheap and simple method to measure the height and to acquire the signal in mountainous region by controlling height touching point. A 2-D modeling technique are used to decompose and analyze the complicated 3-D seismic wave fields. All above techniques can form the base of interpretation method for metal deposit exploration.
