摘要：
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.
