Seepage from the pores of sandstone exposed in deep mines is difficult to block by grouting. In this paper, permeability evolution four subcategories with different pore structures under confining pressures, water pressures and temperatures analyzed experiments. (1) With increasing pressure, permeabilities tested all decrease, but at rates extents. (2) subcategory I1, I2 II1 sandstones increases linearly, while that II2 decreases following a power function low tends be stable high pressures....
In order to verify the applicability of computer numerical simulation method under complex engineering conditions, and solve problem that it is difficult guarantee normal construction underground projects with a depth more than 1 km (it carry out multiple field attempts high-depth if you simply use ordinary calculation method, its accuracy guarantee). For geological conditions an mine 1300 m in Central Plains China, based on finite difference (FDM) high accuracy, using FLAC <inline-formula...
Transversely isotropic rocks are commonly encountered in rock engineering practices, and their strength failure behavior is often governed by the property of anisotropy. The particle flow modeling method was utilized to investigate mechanism transversely subject uniaxial compressive loading. details for establishing models were first presented, then a parametric study carried out look into effect interface properties on mode varying dip angle. smooth joint model incorporated create...
Enhancement of the fluidity and mechanical performance grouting materials has proven to be an effective method seepage prevention in geotechnical engineering. In this research, a microfine-cement-based grout mixed with microfine fly ash (MFA), nano-CaCO 3 (NC), superplasticizer (SP) was designed improve rheological properties materials, particle size distribution, fluidity, spreading ability, bleed capacity, setting time, were studied. A water/solid (W/S) ratio 1.2 selected, contents MFA,...
Computer simulation technology is used to solve various engineering problems in the new century, particularly exemplified by widespread use of numerical research methods. Due complicated geological environment, a mine tunnel with depth 850 m Hebei Province has caused problems, such as large displacements and difficulty implementing support schemes. However, complex conditions make project unique, schemes for other projects cannot be simply copied. In addition, due cost requirements,...
Based on the results of test among joint roughness coefficient (JRC) rock fracture, mechanical aperture, and hydraulic aperture proposed by Barton, this paper deduces proposes a permeability formula single fracture stress‐seepage coupling considering microroughness introduction effect variables microparticle size structural morphology facture surface. Quasi‐sandstone different particle is made laboratory test, respective modification coupled shear‐seepage system JAW‐600 rock. Under...
Herein there is a new approach to improve industrial safety in terms of operation the steel winding tower based on rational design solutions.
One type of seepage water that is difficult to plug by grouting the exuding through pores sandstone in deep underground engineering. Aiming at this problem, paper collected deep-mine samples from Southwest Shandong coalfield, studied pore structure and its influential factors casting thin slices, scanning electron microscopy, mercury intrusion physical property tests, selected five representative permeability classification indicators: permeability, porosity, average throat radius,...
The comprehensive approach including the combination of advanced and new technical solutions with use modern technology opportunities providing real possibility to reduce vertical shaft construction labour inputs, costs time.
The problems of rock outcrop self-sustainability maintenance in mine construction are considered. basic requirements to the applied types supports formulated. new design solutions for some kinds proposed.
Based on supporting failure mechanism and time space function law of surrounding rock deformation, using the FLAC3D numerical simulation analyzes bolt mesh cable coupling support roadway in lagging support.Support covers high strength pre tightening force anchor bolt, sagging cables with rigid support.Through simulation, timing second is determined, distance lag 30m.The engineering practice shows that whole stability can be improved effectively by deep stress roadway.The more stable,...
