Research on Mine cooling measures for Zhangshuanglou coal mine
High-temperature heat-harm of deep mine seriously affects the safety mining of coal mine, so at present the prediction of deep mines underground temperature of and underground climate conditions and the treatment of heat-harm have already become the significant safety technology issues of coal mine production. Mine climate was actually measured along with mainly intake and return air routes of Zhangshuanglou coal mine, using drilling hole to measurement temperature and applying inversion theory of mathematical physics and MATLAB to simulate. The conclusion that the temperature of wall rock of roadways was higher with increasing of depth then to a fixed value while the geothermal gradient was lower with increasing of depth then approached to zero was obtained. Finally the functional expression of the regulating ring of wall rock of laneway was drawn by using the third-order polynomial approximated method, and the deep underground temperature of mining workface 9409, 9109, 7109 and 7505 were predicted, the results of which are accurate, reliable and acceptable.
