Design method for cadmium and arsenic

2020-7-10 · Two type contaminations of cadmium and arsenic can occur in the process of underground coal mining: 1) the development of mining fissures to the ground causes the ground water or atmospheres to link with the goaf, thus bringing the contamination of cadmium and arsenic. 2) Mining fissures spread to overlying strata aquifer, which can cause the connection between the aquifer of the overburden strata and the goaf,
