Gob-side roadways are excavations created during the mining process, serving to alleviate mining-induced stress. Previous studies have predominantly focused on caving method, neglecting examination of failure mechanisms in gob-side roadway associated with continuous and backfilling (CMCB). In this study, focusing Sima Coal Mine, we employed numerical simulation method thoroughly investigate full-cycle stress evolution patterns roadway. The results reveal that upper working face period,...
On the working face below shallow and close coal seams, there are residual pillars. The mine’s ability to operate safely is constrained by pillars’ vulnerability sudden instability powerful ground pressure disasters during withdrawal. This paper uses 31,106 of Huoluowan mine as its research backdrop employs field observation, theoretical analysis, numerical simulation examine strong dynamic load mechanism overlying According pillar’s stress diffusion angle 29 degrees after mining above it,...
Roof weighting failures of pre-driven recovery rooms may cause huge economic losses and even casualties. The excessive dynamic load from the sliding broken main roof rock block causes room inner supports to lose their support capacity during last weighting. Discrete element software UDEC was used investigate surrounding deformation with break at different positions. results show that when room’s length layer’s fracture region is short, immediate subjected high deviatoric stress occurrence...
As a widely-used method of digging roadways in China, gob-side entry driving features specific advantages, such as high recovery rate and good isolation effects. However, under the condition hard overburden, excessive bearing pressure small coal pillars will easily cause serious internal damage run-through plastic zone, leading to harmful gas leakage goaf. Therefore, based on engineering background 18506 working face Xiqu Coal Mine, this paper comprehensively adopts theoretical analysis,...
The k-core, a kind of structure graphs, is maximal connected subgraph with the minimum degree greater than or equal to k, and has been used in many fields. maximum k such that k-core contains u K value u. Especially, for an edge-weighted graph, vertex sum weights all its incident edges. core decomposition problem on static graphs maintenance dynamic have studied unweighted graphs. We improve algorithm suit but it costs too much update values vertices after change large by using directly....
Abstract As we all know, the development of social innovation is inseparable from science and technology. Nowadays, emergence Big Data(BD) has a significant impact on society. In this data age, traditional Teaching Mode(TM) financial management can not meet needs times, teaching to be reformed innovated. context, paper proposes professional research based BD. order adapt trend an accurate TM teaching, use BD technology accurately mine students’ learning characteristics, give targeted plans...
The [Formula: see text]-truss was proposed by Jonathan Cohen in 2008, and it is a widely used as index graph analysis for cohesive subgraph mining. There are two basic problems this area. One the truss decomposition problem, which to compute number of every edge; other maintenance update numbers affected edges dynamic while avoiding recomputation all edges. However, few results known on edge-weighted graphs. In paper, we focus problem Firstly, propose algorithm Then indices, weighted growth...
