“…Besides, we should admit the growth of the stability problem (borehole collapse and shrinkage) [86][87][88] for wells N • 3 and N • 4 by the mechanism described in [89,90]. Some cases of productivity loss in the operation of the degassing network at a mine site are caused by imperfect drilling techniques [91,92] or the limitation of methods of resource extraction by surface boreholes [93][94][95]. In this case, it is rather worth recognizing the insufficient rigidity of the security structures erected in the goaf [96].…”

Decarbonization of the mining industry on the basis of closing the energy generation, on the basis of cogeneration of coal mine methane, and on the internal consumption of the mine is a promising direction in ensuring sustainable development. Known problems of deep underground mining do not allow for realizing the potential of man-made gas reservoirs due to the deterioration of the conditions of development of reserves of georesources. The aim of the work was to improve recommendations for the substantiation of drilling parameters for undermined drainage boreholes for increasing methane production from unconventional coal-gas collectors. The authors’ approach innovation lies in the possibility of using the established patterns of better natural stability of undermined boreholes to optimize them as spatial orientation parameters in an existing drilling passport for the improvement of methane extraction productivity. For this purpose, smoothing (LOESS) of the experimental data of two similar types of wells was used; then deterministic interpolation methods in combination with a three-dimensional representation of the response function in “gnuplot” were used. As a result, it was found that the increase in the inclination angle from 40° to 60° leads to a significant transformation of the model of the studied process, accompanied by a decline in the dynamics of methane emission and a decrease in the distance of the productive work zone of this type of well from 13 to 5 m before the roof landing, which then is replaced by a sharp increase in the productive work zone up to 35 m ahead of the longwall face. This allows under specific conditions for recommending increasing the productivity of methane capex from technogenic disturbed coal-gas reservoir replacement of wells with a smaller angle of rise to the transition to a more frequent grid of clusters from wells #4.

The issues of the evaluation and prediction of the reliability and testability of mining machinery and equipment are becoming particularly relevant, since the safety of technological processes and human life is reaching a new level of realisation due to changes in mining technology. The work is devoted to the development of a logical model for analysing the controllability of mining equipment. The paper presents a model of reliability of the operation of mining equipment on the example of a mine load and passenger hoist. This generalised model is made in the form of a graph of transitions and supplemented with a system of equations. The model allows for the estimation of the reliability of equipment elements and equipment as a whole. A mathematical and logical model for the calculation of the availability and downtime coefficients of various designs of mining equipment systems is proposed. This model became the basis for the methods to calculate the optimal values of diagnostic depth. At these calculated values, the maximum value of availability factor will be obtained. In this paper, an analytical study was carried out and dependences of the readiness factor of parameters of the investigated system such as the intensity of control of technical systems, intensity of failures, etc., were constructed. The paper proposes a mathematical model to assess the reliability of mine hoisting plants through its integration into the method of improving the reliability of mine hoisting plants.

More than half of the global demand for energy resources is covered today by oil and natural gas, and according to various forecasts, it is expected to grow 1.5–2 times greater over the next 30–50 years. This creates serious prospects for the development of the national oil and gas sectors of various countries, including Russia. Modern industry challenges create significant restrictions for the development of Russian oil and gas resources, and considering their predominant technological nature, the key solution is the increase in internal technological potential, in particular through the implementation of engineering projects aimed at creating the necessary technological solutions. This article presents an approach to the development of a conceptual management framework that will allow for the effective implementation of oil and gas engineering projects. The methodology of the research includes desk studies, systematization, the expert method (including interviews and questionnaires), grouping, generalization, and algorithm design techniques. The results of the study showed that effective implementation of engineering projects should be based on a systematic management approach, one of which is the TRA process. This article analyzes the TRA methods, on the basis of which key project readiness indicators are identified. Based on a literature review and the expert method, the relevant readiness indicators necessary for the assessment of oil and gas engineering projects are substantiated. Given these indicators, the authors proposed a framework for a comprehensive readiness assessment of oil and gas engineering projects and developed an algorithm for management decision-making on project implementation.
