Abstract
The Bureau of Mines has successfully tested a method to simulate methane gas flows from face areas through the returns of noncoal mines. This technique involves releasing a small quantity of tracer gas at a working area and sampling for that gas downstream in the return airways. By measuring the reduction in the tracer gas concentration, a reduction for any face released volume of methane gas can be calculated. This information is useful in selecting locations for methane monitors and in deciding the necessity for permissible equipment in the returns.
