Abstract:

For environment protection in mining areas in northwest China,we developed a CTSRM(comprehensive test system by radon measurement) to measure radon radioactivity and detect dynamic evolution characteristics of mining-induced fractures in overlying strata.It was used to simulate the relationship between the dynamic evolution characteristics and radon concentrations of 33201~# coalface at Bulianta coal mine in Inner Mongolia,and feasibility of the method was validate.
