摘要
A series of geogas models were built to study the element transportation regularity in the lead-zinc ore and its surrounding rocks under the action of ascending gas flows.The amount of elements transferred out of the simulated ore and rock layer were determined by ICP-MS.Then,the transportation rates of various elements were estimated.The results indicate that the elements transferred out of the ore and rock layer can continually accumulate in the above catcher under the action of ascending gas flows.The transportation rates of elements are different from each other.A large concentrations of ore-forming elements in the ore body would inevitably result in high rates of transportation,forming geogas anomalies above the ore body.
