Underground construction is a prerequisite condition to carry out the pros and cons trough channel wave seismic prospecting. The current condition of the underground construction is still no clear evaluation of the technical indicators and theoretical basis. The fuzzy comprehensive evaluation method analyzed the problem comprehensively which exists the process of channel wave seismic prospecting construction condition the assessment tasks evaluation, and provides a certain level according to the actual evaluation of construction conditions. The assessment result is objective, scientific and reasonable. Furthermore, it can provide the necessary theoretical basis for the design and construction of post-data processing and interpretation, optimize the construction process and improve the quality of data collection.
