In order to improve the permeability of soft coal seams with low intensity and by hydraulic fracturing, an elastoplastic softening damage model has been established, which takes into consideration lower elastic modulus tensile strength higher pore compressibility plastic deformation. The then was implemented FLAC3D finite difference software be verified on-site results Number 2709 coalface in Datong mine, China. modelling fracture-influenced radius show good consistency results. Then...
Coalbed methane is always a major hidden danger that affects mining safety in coal mines. In the study of seam water injection to control gas disaster, increase free content helpful destroy integrity and promote flow fractures. However, when fills fracture space, it will resistance gas, then reduce extraction efficiency. At present, there currently no mathematical model describing effects combines these two aspects on drainage. this study, series experiments were conducted differences...
Superheated steam‐enhanced steam‐assisted gravity drainage (SSE‐SAGD) is a promising enhanced oil recovery method. However, the existence of aquathermolysis reactions makes development process more complex. In this paper, application potential SSE‐SAGD in an oilfield was analyzed based on estimated and production cost. A numerical model with established, after validation, effects steam superheats chamber's expansion were by taking heat loss into account. Subsequently, cumulative enthalpy‐oil...
Gas outburst has always affected the safety of coal mining. To eliminate this risk by high-efficiency extraction coalbed methane (CBM) in 4102 working face number 3 seam Hebi Number mine, a model CBM was established which considering mining impact adjacent 4101 face. In model, coupling relationships between stress, desorption, and migration were analyzed. Moreover, we also studied changes pressure, plastic failure scope, permeability during then verified results with field data. And on...
The rapid expansion of urban areas due to China’s booming economy has led a conflict between people and vehicular traffic. Consequently, rail transit, represented by subways, become the primary mode transportation for residents. However, influence soil damage on tunnel deformation is often overlooked in research safety soft tunneling, leading discrepancies results predicted models actual settlement tunnels. In this study, investigation mechanical strength testing were carried out analyze...
Aiming at remote pressure-regulating system and based on dynamic-characteristics fundamental equation of distributed-parameter model in hydraulic pipelines, the mathematical pipelines is deduced. The condition resonance pipeline discussed under controllable maximum stiffness coefficient. results show that, controllability a depends length to certain extent. Thus two conditions must be derived if wants work normally, one coefficient other suitable avoid resonance.
