Original Rock Temperature Measurement and Heat Resource Analysis of Chengjiao Mine

Chengjiao mine belongs to hot disaster mine of high temperature.Shallow holes temperature measurement methods are used in original rock temperature measurement,and six measuring points are tested in underground mine.Precision barometer,kata thermometer,air-flow meter and other test tools are used in the field measurement,so as to measure the atmospheric thermophysical parameters change in wind intake system of 2501 working face.On this basis,the quantitative analysis is carried out on the heat sources of 2501 fully mechanized working face,which provides the basis for artificial cooling measures establishment.
