METHOD FOR PREDICTION OF METHANE CONTENT OF PRODUCTION AREAS OF COAL MINES

摘要

The invention relates to mining and can be used at prediction of methane content of underground mines and production faces on basis of which one designs ventilation of coal mines and separate working areas, selection of methods and means for control of gas liberation, determination of optimal by gas factor loads on production face and solving other problems related to provision of safe conditions of work. In the method for prediction of methane content at working areas of coal mines due to analytical description of structure of dynamical row of methane content one gets possibility to take into consideration in explicit form change of factors that affect and to predict methane content at stage of designing working area with implementation of current correction of predicted values with working out operating face, this decreases probability of error and increases effectiveness.
