The concept of risk-based technical solutions for the protection of coal mine workings

Abstract

Annotation The concept of risk-based technical solutions for the protection of coal mines workings is outlined. The initial data of effective risk management methods are substantiated. A mixed method of risks assessment has been used. The method involves building a matrix of consequences and probabilities by ranking them in the form of tables. The following data have been used as initial data: location, method and parameters of the workings protection, additional measures to manage the state of the rock mass around the workings, cost of certain types of work and material costs, purpose and term operation of the workings. Technical solutions for the protection of underground workings in coal mines to increase labor safety and reduce environmental and financial risks are substantiated. Initial data for effective methods of risks management in the protection of workings in difficult mining and technical conditions have been prepared. It is recommended to use these data as the basis of the new regulatory framework.
