Long-wall coal mining method is using a large scale automatic equipment for coal production and it makes tens of thousands per day at the intensive mine site. Before we carrying out long-wall mining method, many research and pre-processing are necessary to be performed. Among those processes, ventilation and exhaust system is the most important part to emit methane gas of coal bed. Methane gas emission is necessary to perform efficiently in the short or long-term during the development or pre-development period. About long-wall mining method, there are many studies of methane gas control system were conducted. The studies were using input data with variety of conditions for using artificial neural network systems which can help us to infer methane gas flow rate and concentration. And also, when we using Long-wall mining method, the subsidence is inevitable. However, if we could estimate the volume and scale of subsidence at right time, we could minimize the damage which caused by subsidence.
