“…According to the kinetic theory [40], both traditional CFD method and LBM can satisfy the macroscopic Navier-Stokes equation in their continuous forms. However, Navier-Stokes equations are the target for LBM while the starting point for the traditional CFD methods, and these two methods also differ, not only in the spatial discretization forms, but also in the temporal discretization forms.…”

Mine safety is of primary concern in the underground coal mining system. At present, there is a lack of an efficient platform to manage the numerical simulation procedure and inherent spatiotemporal data for coal mine disasters. This necessitates the coupling of spatiotemporal model with geographic information system (GIS) in practical application. Here, a novel spatiotemporal model tightly coupled with GIS is presented to improve the model-data integration. Such tight coupling is achieved by developing a lattice Boltzmann method (LBM) based turbulent model with an underlying shared FluentEntity model within the LongRuanGIS platform. The case study and comparison with the traditional computational fluid dynamics (CFD) method demonstrated that the platform is capable and effective in providing functionalities for lattice domain decomposition, simulation, visualization and analyses, as well as improving the computational efficiency. The proposed approach and platform, promising for the disaster prevention, offer a template for future GIS-Model integration and also applicable for other underground coal mine disasters.

“…Li et al [39] designed a Longruan GIS platform to control and monitor mine disasters induced by high crustal stress, gas thickness, and seepage water pressure in an underground coal mine. Roadway, 3D geological, and working face modeling were performed based on an irregular triangulated network using a geomechanical parameter database, which was related to hydrogeological, gas distribution, crustal stress, rock mechanical, and rock classification data.…”

In this study, geographic information system (GIS)-based methods and applications utilized for mine development were reviewed. Three types of GIS-based studies, namely studies on mine planning, operation, and environmental management, were examined to describe the role of GIS as a decision-making support tool in mine development. This review was conducted by classifying previous GIS-based studies into several subtopics that pertain to mine development activities and the range of environments to be managed. Because the use of GIS is appropriate for spatial data management related to ore deposits and mine environment conditions at various scales, the applications of GIS-based methods in mine development could be expanded further.

“…With the VENTGraph simulation software and mathematical model for air flow, Dziurzynski et al [16] compensated and balanced air quantity in determining the roadway pressure, and numerically investigated the optimization of mine ventilation network parameters. Li et al [17] developed the decision-making system of deep mining safety control based on Longruan GIS and simulated mine ventilation system successfully to study ventilation system changes during deep coal production. Consequently, the mining safety and efficiency were increased.…”

To accurately correct wind resistance acquisition problems during the ventilation reconstruction and then calculate the air quantity in various roadways, taking the reconstruction of ventilation system in Shaqu Coal Mine of China as an example, the "calculation-feedback-correction" mechanism for adjusting roadway wind resistance was proposed based on the Ventsim simulation technique. Wind resistance was calculated and the change of air supply-demand after the reconstruction of the ventilation system was analysed using the proposed mechanism. The reasonable isolation reconstruction program was verified. Finally, the relationship between opening area of air window and wind resistance after the isolation reconstruction was fitted by the Fluent technology and the optimal opening area of air window was calculated. Results show that: (1) the ventilator area of the south upcast inclined shaft 1# operates unstably after the isolation reconstruction; (2) when the opening area of air window reaches at least 3.28 m 2 , the ventilator works normally and steadily. The results also demonstrate that good ventilation effect can be achieved by adjusting resistance reduction and setting the optimal opening area of air window which conforms to the actual status of ventilation systems.
