A study based on 2D seismic prospecting method of distributed real-time data acquisition system

摘要

In allusion to problems such as complexity of coalfield geological condition, lack of experience of geophysical prospecting, low sensitivity and poor resolution of traditional seismometers in Enhong coal mine area of Yunnan Province, this paper puts forward a real-time data acquisition method based on distributed acquisition system. The collected real-time data are of high-precision and high-reliability after being compared with those geological section maps via extractive geological samples from a series of misering engineering. Thereupon this method is proved to be able to ascertain accurately coal seam strike of northwest shallow seam and southeast deep seam, occurrence conditions of stable distance between coal seams, and development situations of structures often faults, two anticlines and one syncline in test sections. The imaging data from test provide scientific instructions and reliable data reference for reasonable layout of mining face and mine roadway, as well as high efficiency and safety underground mining.
