METHOD TO INCREASE SAFETY AT COAL EXTRACTION IN DANGEROUS BY METHANE WORKINGS AND COMPLEX OF MEANS FOR ITS IMPLEMENTATION

摘要

Method to increase safety at coal extraction in dangerous by methane workings relates to mining and is in control of concentration of methane in atmosphere of extraction working by length of extraction working in several points. It can be used for prediction of explosion safety of mine atmosphere along line of working. One determines rate of concentration and time in which it can come to dangerous values in each of control points, and gives notification signal. Complex of means for implementation of method has block of integrated evaluation of danger by measured parameters, block for calculation of value of predicted value being measured and drawing histograms for each cycle of indicator interrogation. Continuous analysis of change of parameters of atmosphere is provided and operative notification on pre-emergency situation coming to existence.
