The article discusses the possibility of 3D computer modeling tools complex use based on the mathematical processing of the gas emissions from TPP cleaning process. The authors propose to consider an approach to designing a site for capturing solid particles in gas emissions that appear during the production activities of an industrial enterprise by modeling a technological site in various programs. Mathematical processing with the use of the E-network device and the creation of a 3D model enables to plan a site for capturing solid particles in gas emissions, choose the appropriate technology and thereby ensure the ecological effect of both existing and projected power plants. The authors present the results of processing the technological process of gas purification at thermal power plants in terms of E-networks using mathematical processing in the Simulink application, which displays a device model from the standard units available in the program and performs the necessary calculations. 3D models of individual pieces of equipment selected on the basis of mathematical processing calculations in the Simulink application were created using computer 3D modeling in a graphical editor. A 3D visualization of the technological site for capturing solid particles in gas emissions was carried out, enabling a visual display of the planned site at the design stage, which, if necessary, will allow an easy introduction of modifications to the project.

The article considers the possibility of joint application of mathematical processing and computer 3D modeling of the technological process line for processing ash and slag waste from thermal power plants (TPP). The authors suggest considering an approach to the design of the ash and slag waste processing site by mathematical processing and 3D computer modeling. The mathematical processing with the help of E- network device and the creation of a 3D model allows to plan the site for processing ash and slag waste, select the appropriate technology and thereby ensure the environmental effect of both existing and projected power plants. The authors present the results of processing the technological process of recycling ash and slag wastes of TPP in terms of E-networks using mathematical processing in the Simulink application, which displays the device model from the standard blocks available in the program and performs the necessary calculations. 3D models of individual equipment units selected on the basis of mathematical processing calculations in the Simulink application, were created using computer 3D modeling in a graphical editor. A 3D visualization of the technological section of ash and slag waste processing was performed, which allows to clearly show the planned section at the design stage, which, if necessary, will allow to easily make changes to the project.

“…Scholars in the open-air mining industry have attached great importance to the research of the waste dump. Its stability analysis is one of the hot issues in the field of open mining and geotechnical engineering [6][7][8][9][10]. With the development of open-pit mining, the stability of open-pit high slope and inclined shaft has also become one of the key technical problems in mine resources development [11].…”

The stability of open-pit mining is a hot issue in geotechnical engineering. A mining railroad is in operation on the slope where the east exhaust inclined shaft and the east sand injection inclined shaft on the Laohutai Mine are located, and it was necessary to determine whether railroad vibration would have an impact on the safety of the inclined shafts. With this project as the background, the dynamic response of the slope with inside two inclined shafts was conducted under train loading. A three-dimensional numerical model by using PLAXIS 3D was established to analyze the stability of the slope. The results show that the dynamic reaction caused by the full-loaded train is significantly greater than the no-load train. The safety factor of the slope under the dynamic load is 1.201, and the maximum displacement of the slope which occurred in the gravel layer directly beneath the train track is about 5 mm. The acceleration responses of the two inclined shafts are almost consistent. The maximum horizontal and vertical acceleration occur at the epidote weak layer. The acceleration directly below the load increases significantly. Therefore, it can be considered that the slopes are stable under the action of train vibration, and the influence on the two inclined shafts is small and negligible.
