Experimental Study of Three-Dimensional Time Domain of Water Evaporation from Goaf

Previous theories on coal spontaneous combustion (CSC) prevention and control mostly focused how to improve the CSC-inhibiting effect instead of failure inhibitors. Due influence air leakage in goaf, inhibitors water evaporate continuously, thus making inhibit weakened or even null. complex environment inside it is difficult for personnel enter collect data such as moisture. Therefore, a three-dimensional model mining area was built study changes moisture goaf under different conditions. The analysis experimental results shows that larger volume is, faster evaporates goaf. body reduced from 30% about 5% 15, 11 7 days when 0.02, 0.03 0.04 m3/s, respectively. law evaporation at times locations also studied found location- time-dependent.
