Two critical factors, namely intense precipitation and intricate excavation, can trigger rock mass disasters in mining operations. In this study, an indoor rainfall system was developed to precisely regulate the flow intensity of precipitation. A large-scale model experiment conducted on a self-designed physical simulation platform investigate failure instability high-steep slopes under unsaturated conditions. The real-time reproduction progressive process enabled determination revealed...
With the ending of deep-concave open-pit phosphorite extractions and gradual exhausting shallow mineral resources, stoping seams has entered or will enter into underground mining. Particularly for excavating slightly inclined thin medium-thick orebodies, roof surface control under different mining methods is crucial safe efficient exploitations. In this study, study area located in Kunyang Phosphorite Mine characterized by deposits. Based on occurrence conditions, orebody thickness, dip...
In order to study the stability of rock layers and change in volumetric water content at different stages mining under an environment heavy rainfall, a self-developed large-scale open-pit-to-underground-mining similar physical model was used, intensity continuous rainfall set 40 mm/h. The results this show that fissures accelerated instability strata, when spreading they were prone form subsidence cracks produce collapse zones. is closely related formation. An ‘arch-shaped zone’ formed...
Cemented paste backfill (CPB), a technology placing the solid waste into mined-out stopes in mine through pipeline transportation, has been widespread all over world. The resistance loss is an important parameter for transport, which significantly affected by slurry characteristics. However, coupling effect of inlet velocity (IV), particle mass concentration (PMC), and size (PS) not well evaluated diagnosed. Hence, CFD-based three-dimensional network simulation CPB flow L-shaped pipe at...
This research examines how rainfall and mining affect the slope damage resulting from transition open-pit to underground mining. Using unmanned aerial vehicle (UAV), Huangniu of Dexing Copper Mine was fully characterized, experiments were conducted on rock samples appropriate sites. First, mechanical properties measured. Then, parameters similarity simulation derived based theory. Subsequently, rainfall, slope, data acquisition monitoring systems designed. Finally, mass failure with...
Correctly predicting the stock price movement direction is of immense importance in financial market. In recent years, with expansion dimension and volume data, nonstationary nonlinear characters finance data make it difficult to predict accurately. this article, we propose a methodology that combines technical analysis sentiment construct predictor variables then apply improved LASSO-LASSO forecast direction. First, textual content historical transaction are crawled from websites. Then...
The accumulation of original phosphogypsum (OPG) has occupied considerable land resources, which have induced significant environmental problems worldwide. OPG-based cemented paste backfill (OCPB) been introduced as a promising solution. In this study, water-washing pre-treatment was used to purify OPG, aiming optimize the transport performance and mechanical properties backfills. overall results proved that in treated phosphogypsum-based (TCPB), altered particle size distribution can...
Spalling failure is a typical phenomenon after excavation and unloading of deep, hard brittle rock mass, which seriously threatens the safe construction deep roadways (tunnels) other projects. From engineering viewpoint, it essential to accurately evaluate range depth surrounding spalling failure. perspective laboratory site, strength formation mechanism were statistically summarized analyzed. Under uniaxial low confining pressure conditions, when load reached damage stress, cracks in...
A new model is established to analyze mining stope stability, using variable weight theory calculate the index for each factor in different stopes and unascertained measure evaluation technique predict risk grade of stability. In this model, an system by virtue 7 most important factors established, including rock saturated uniaxial compressive strength, quality designation, joint fissure, span, condition pillar, groundwater seepage volume, rate supporting pit roof. And divided into 5 grades...
Recently, more and mobile devices have been connected to the Internet. The Internet environment is complicated, network security incidents emerge endlessly. Traditional blocking killing passive defense measures cannot fundamentally meet requirements. Inspired by heuristic establishment of multiple lines in immunology, we designed prototyped a Double Defense strategy with Endogenous Safety Security (DDESS) based on multi-identifier (MIN) architecture. DDESS adopts idea zero-trust network,...
Industrial Internet identifiers have the characteristics of heterogeneity, off-site, and foreign ownership. Traditional identifier systems encountered many problems, such as IP address exhaustion or difficulty in addressing routing, which cannot meet demands numerous heterogeneous interoperable objects. At same time, they also face various security risks. In this article, we propose multi-identifier network for Things (MIN-IIoT), a universal system named architecture Internet, supports...
