Research and development of a method for predicting micro-fault fractures in coal seams using artificial intelligence methods.\u0000\u0000Methodology. To carry out the study, a neural network of the sing structure was formed. The training of the network was based on the principles of natural selection, which is the strongest one. The implementation of this principle was designed to support the genetic algorithm. Each network was tested for fitness, proportional to its ability to predict, and the best one was used for forecasting. The forecast was made in such a way that from the base point the forecast was made for the entire project site.\u0000\u0000Results. The research was conducted to develop a method for predicting the coordinates and amplitudes of low-amplitude disturbances using neural networks and genetic algorithms.The method consists in training a neural network based on reliable data taken from mining plans and, after a certain number of trainings, forecasting micro-fault discontinuous disturbances on the project site. The parameters of the violations revealed by tunnelling and cleaning works are used as training data.\u0000\u0000Originality. The method of forecasting micro-fault discontinuous disturbances using artificial intelligence allows predicting the presence and probability of distribution of disturbances in the predicted area. The main advantage of this method is the minimal cost with sufficient reliability. This favourably distinguishes it from the known methods. The application of this method does not require the use of special equipment in mine conditions, which significantly reduces the labour-intensiveness of the forecast. The efficiency of this method allows you to quickly and in a short time make a forecast on a given site, which contributes to the fastest possible commissioning of new mining fields.\u0000\u0000Practical value. The proposed method can be used to predict micro-fault discontinuous disturbances in the extraction fields of mines in the Ukrainian Donbas to assess the reliability of working out the extraction pillars and ensure the stability of the preparatory works due to their rational location. At the same time, the forecasting technique is being improved, taking into account the main characteristics of the physical process of the genesis of micro-fault discontinuous disturbances.","PeriodicalId":344647,"journal":{"name":"JOURNAL of Donetsk mining institute","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126056758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification of the main directions of evolution of scientific researches concerning development and improvement of fire protective reactive coatings of intumescent type for steel constructions. Methods. Analysis of literature sources, study and generalization of information, classification and modeling of chemical processes. Results. As a result of the performed researches it has been shown that of all the developed reactive fire protection systems for increasing the fire resistance of steel structures the intumescent composition of ammonium polyphosphate/ pentaerythritol / melamine / polymer is the most widespread and economically justified. To reduce the cost of fire protection measures, it is necessary to improve the coatings of the intumescent type in the following main areas: increasing of fire protection efficiency with a decrease in the thickness of the fire protection layer; prolongation of life time with strengthening of resistance to external factors; reducing the cost of the prescription composition of intumescent paint due to the use of nanomaterials. Scientific novelty. It has been established that nanoclays, nanooxides of metals and silicon, LDH compounds and their analogues should be considered the most promising and multifunctional. The presence of nanomaterials in intumescent compositions allows to increase the environmental parameters of fire-retardant treatment due to the rejection of halogen flame retardants, boron compounds, formaldehyde resins. In addition, the presence of nanocompounds in intumescent coatings significantly reduces smoke in fire. Practical significance. The conclusions obtained from the literature review are of practical importance for the development of new approaches to the design of fire-fighting materials with improved performance through the use of nanomaterials, which provides a strong fire retardant foam char layer and provides rigidity of the insulation frame.","PeriodicalId":344647,"journal":{"name":"JOURNAL of Donetsk mining institute","volume":" 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113950889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To develop a new approach to the design of processes for the development of mineral deposits based on the justification of the area of rational exploitation. Methods. To develop a new approach, a decomposition approach was used to represent the cycle of field development; optimisation algorithms on networks and graphs – to find the optimal solution; marginal analysis – to justify the rational volume of mineral extraction. Application of these approaches allows developing a decision support system. Findings. A new approach to the evaluation and selection of parameters is presented, a characteristic feature of which is that the mineral itself is not considered “as the final product”to be extracted, but only as an intermediate link in the structure of energy generation, metal smelting, etc. This allows considering the process of exploitation through the change in the state of reserves, which in turn forms the development strategy. The development strategy involves the construction of scenarios (economic, environmental) within the framework of which the “narrow” task related to the organisation of work, cost optimisation, etc. is solved. It is proved that the efficiency of the technological scheme is an integral indicator, which is formed by a group of technological, operational, economic factors within the field of rational design and depends on functional relationships. As an example, the technological processes of a coal mine as a component of an electric power generation system are considered in a complex. Originality. The scientific novelty of the work is to establish the laws of formation of the efficiency of the processes of development of mineral deposits. It was established that the increase in the efficiency of the processes of mineral deposits development is achieved based on increasing the reliability of technological schemes, which is directly proportional to the functional relationships and inversely proportional to the resources involved, by optimising network models that demonstrate the heterogeneity and probabilistic nature of the formation of the level of efficiency. For the first time, the processes that accompany the development of mineral deposits are considered through the change in the state of mineral reserves, that is, the task of designing a separate process is considered as an intermediate link in the overall system of production links. It is established that for the design of field development processes, it is necessary to substantiate the area of rational operation, which involves a comprehensive representation of the field development cycle in the form of a hierarchical structure, based on the category of “quality”, which in turn forms strategies; strategies form scenarios, and scenarios contain parameters; optimization of each parameter involves the assessment of priority control factors.
