Comparison and Analysis of Mine Gas and Heat

Abstract

By analyzing the definition, mechanism of action, determination methods and damage degree of mine gas and heat, a conclusion can be reached that these two types of object (or be known as physical quantity) have similarities to a large extent. First, both of the mine gas and the mine heat are caused by field changes that respond to the mining activities. Second, we can use relative equipments and the element method to do quantitative determination and analysis. Third, the phenomenon which gas and temperature exceed the limit occurrs frequently in the return corner and other specified place. According to the above similarities, we proposed that the exploitation of mine heat should be brought into the mine green mining technology system, to form the mining technology of extracting coal, gas and heat together, which can enrich and perfect the green mining technology system.
