The algorithm for determining an optimal system of routes for the mine ventilation and safety engineering masters for the purpose of monitoring aerodynamic parameters of the ventilation network in mines

Route control of the mine aerogasdynamic parameters is organized in such a way that the obtained information can supplement the information of the unified telecommunication system for dispatch control and automated control of mining machines and technological complexes or another similar system installed in the mine making this information more exact, promptly if possible, without duplications. The route control system is formed from the practical considerations with taking into account the data of the stationary system. Due to the joint functioning of stationary and route control systems with accounting the previous changes of aerogasdynamic parameters, it will be possible to build a predicted trajectory of such a change, which will improve reliability, optimize the control structure and more exactly predict the occurrence of emergency situations. In this article, the authors formulate the main definitions and properties of the route control system and the problem of creating the routes covered the entire mine ventilation network with a given number of control points. An algorithm for constructing a route control system is characterized with taking into account economic and ergonomic conditions, time factor and safety requirements. To solve this problem, it is proposed to use the method of sequential improvement of admissible plan. The essence of the method is that, having received a certain solution (an admissible plan) as an initial approximation, the measures are proposed for improving it till further improvement becomes impossible. The "improvement" here means more complete satisfaction of the proposed criterion for minimizing total time of the master travelling for executing his work on the route. Improvement of the admissible plan is carried out by the Monte Carlo method. The possibility of duplication of data obtained from an automated system and by route control is analyzed, and a reduction of the basis of control stations is grounded. The set of routes for monitoring parameters of the ventilation network elements by mine experts chosen in this way will reduce the risk of obtaining incomplete information about its aerogasdynamic state, and cross-monitoring of measurements within the transversal of the bases of two components of the control system will improve reliability and accuracy of the monitoring.
