Prediction and analysis model of explosive and inflammable gas accumulation in air in oil mines

The working conditions in mines in viscous oil fields are characterized, and the risks related with underground explosions of steam and gas/air mixtures are identified. The relevance and the objective of the research are formulated and substantiated on the basis of the review of legal, scientific and technical documentation in use in oil recovery and in other mining industries, as well as the other information sources that address the issues of underground oil recovery. The goal of the research is to develop a methodological approach to the explosion hazard prediction in oil mine air, and to determine the operational conditions predisposed to origination of an explosion hazard in mine air. One of the components of the research procedure is a method proposed by the authors, which consists in mathematical modeling of dilution of explosive chemical agents with fresh air. From the experimental evidence, the authors put forward an algorithm for estimating explosive hazard of air in oil mines. The algorithm uses the method of predictive calculation of explosive chemical agent concentrations in mine air. The influence of physically bound water content in oil emulsions on the lower value of the flame spread temperature range is determined. The experimental results prove the ability of high viscous oil to generate explosive steam and gas/air mixtures as a result of heating under conditions of underground fires. Finally, the article gives the conclusions and recommendations on using the research findings in management of professional risks associated with explosions of steam and gas/air mixtures in oil mines.
