Innovative Activities in the Sphere of Mining Process Management

Abstract

The purpose of this paper is to propose a new methodological approach to complex assessment of coal-mining enterprises basing on the evaluation of technological schemes from the viewpoint of their susceptibility to innovations. To solve the specified problems, a complex method has been used. The method involves geometrical interpretation of a task of determining boundary parameters of technological schemes, application of criteria-based estimations for determining a level of production efficiency, and use of complex index of economic re liability. For the first time, optimality criteria for innovation management in coal industry have been proposed; they take into consideration a level of organization of innovations, organization of innovative production system, and organization of innovative production process. A complex index “internal potential of technological networks” has been developed, being one of the essential parameters for evaluating coal mine conditions. It has been identified that its formation is the result of the influence of certain factors determining the underground mining efficiency and, first of all, the coal mine property—spatial development. According to the represented concept, a policy of optimal control for maintaining the operating mine capacities is based on the evaluation of remained reserves, substantiated planning of a stoping line, and correspondence of extraction equipment to the operating conditions. It is possible to increase the concentration of production by redistributing the remained reserves and integration of mines by mining operations; that makes it possible to concentrate resources within those parts of a mine field where the effect will show its maximum. Modelling of such problems is based on a system of constraints without any requirements for providing the planned mine loading, obligatory in the past. Analysis of the indices of efficiency of coal-mining technological schemes and accounting of the developed factual system of indices have helped elaborate recommendations concerning the use of optimality criteria in the organizational tasks of assessment of the potential of technological scheme of mines. Further application of graphs and network models will allow optimizing the mining production parameters. Consequently, the carried out research has resulted in a new system as for innovation management in a mining complex.

Water Extracts from Waste Rocks of the Coal Industry of Chernvonograd Mining Area (Ukraine): Problems of Environmental Safety and Civil Protection

“…The environmental safety rate and the risks of emergency situations are largely determined by the pollution of the hydrosphere by insufficiently treated municipal wastewater [1,2] and industrial effluents [3,4], pollution of the lithosphere by domestic solid waste [5,6] and industrial [7,8] waste. A significant deterioration of quality of the natural environment (both at the local and regional levels) is observed in conditions of intensive development of the mining industry [9,10]. Production activities related to hard coal mining and its beneficiation within the limits of the Chervonohrad Mining Area (ChMA) of the Lviv-Volyn Coal Basin (LVCB) are accompanied by the formation of underground cavities, which subsequently cause subsidence and flooding of territories [11][12][13] accumulation of significant masses of empty waste rock, which leads to the formation of rock dumps (tericons) near mines, which are capable of spontaneous combustion [14,15] and are a source of toxic elements and compounds in the environment.…”

Mathematical model and methods for solving heat-transfer problem during underground coal gasification

“…This fuel is particularly suitable for use in combined power generation cycle, which is based on material, financial, human and organizational resources [3]- [5]. Of course, evaluation of such technology must be substantiated by taking into account discounting and financial activity of the enterprise and its process management [6]- [8].…”

Management of the longwall face advance on the stress-strain state of rock mass

“…The current economic situation in Ukrainian mines prompts the search for internal reserves to improve the efficiency of mining operations. Primarily, such a situation is typical for state-owned mines [1]- [3]. In the context of such enterprises, significant lack of budget funding is the component factor preventing from purchase of new equipment and renovation of fleet of powered systems.…”
