Severe gas disasters in deep mining areas are increasing, and traditional protective coal seam is facing significant challenges. This paper proposes an innovative technology using soft rock as the absence of appropriate seam. Based on geological engineering conditions new horizontal first area Luling Coal Mine Huaibei, China, impacts different parameters soft-rock pressure-relief effect protected were analyzed through numerical simulation. The unit stress seam, which was less than half...
The protective layer mining method of the traditional deep coal seam in has been confronted with great challenges, and it is difficult for gas to be extracted together. Taking occurrence conditions III1 area Luling Coal Mine located at Huaibei, China, as engineering background, influence law lithology on stress environment front stope was analyzed by theoretical analysis numerical simulations. mining‐induced mechanical effect coal‐rock mass studied under different modes. results showed that...
Abstract Various types of porous media materials inherently contain pore structures different scales, ranging from nanoscale to millimeter scale. Due the limitations existing imaging technology, it is challenging and intractable for any single method obtain characterize multiscale structure features accurately comprehensively. To address issue, according inherent logical correspondence mutual conversion relationship between different‐scale image pixels, we propose an improved universal...
Abstract Biogenic coalbed methane is produced by biological processes mediated synergistic interactions of microbial complexes in coal seams. However, the ecological role functional bacteria biogenic remains poorly understood. Here, we studied metagenome assembled genomes (MAGs) Bacillales and Clostridiales from seams, revealing further expansion hydrogen acetogen producers involved organic matter decomposition. In this study, were dominant orders (91.85 ± 0.94%) cultured a total 16 MAGs six...
Coal and gas outburst is the extreme instability caused by stress, gas, coal. In this review article, dominant factors inducing of were summarized; geologic features typical cases effects tectonic movement on outbursts analyzed; stages with considerations to divided. It was found that factors, including buried depth, movement, composition, coal seam conditions, overlying/underlying rock mining mode, control influencing (stress, coal). Among them, key outburst. Influenced primary structure...
In order to study the mechanical properties and energy dissipation of gas coal under dynamic static loads, loading impact tests different strain rates were carried out by testing systems SZW‐1000 microcomputer servo pressure tester separated Hopkinson bar (SHPB) for in Panxie Coal Field Huainan City. test, influence laws various patterns on properties, failure characteristics, sample analyzed. The results showed that stress‐strain curve load had no micropore compaction stage compared with...
The issue of quality-related fault detection in the industrial process has attracted much attention recent years. partial least squares (PLS) is considered an efficient tool for predicting and monitoring. modified (MPLS) extended algorithm solving oblique decomposition PLS, however, study indicated that loss quality variable information may affect prediction MPLS algorithm. Furthermore, rate traditional statistics static control limit low, existing dynamic certain limitations. Therefore, a...
To scientifically and effectively manage exhaust pollution in underground confined spaces reduce hazards from personnel exposure, a systematic study of the distribution characteristics diesel locomotive emissions mines is needed. Aiming at large coal mining operations, an experimental platform for physical simulation vehicle transport restricted designed created. The Hongliulin Coal Mine Shaanxi Province, China, used as prototype, consists face system, ventilation emission monitoring...
Coal mine dust is an important factor leading to occupational diseases of workers, however, it remains poorly understood about the non-viral pathogens in coal dust. In this study, bacterial communities total and respirable from different laneways Hongliulin (Shaanxi, China) were analyzed by PacBio high-throughput sequencing. The results showed no significant differences number, diversity structure laneways. Gammaproteobacteria, Alphaproteobacteria Betaproteobacteria numerically dominant...
The key for dust control of coal mine is to clarify the concentration distribution and sedimentation in different areas. Both similarity experiment numerical simulation method have certain restrictions are quite from actual situation on site. In order study regularity large mining height, “filter membrane method” adopted this paper, i.e., dry weigh filter before after sampling, collect respirable zone face calculate based a main airway 100 m. result shows that: A amount will be produced...
Abstract Soft tectonic coal commonly exists in and gas outburst zones. The physical simulation experiment was carried out to reproduce the influences of soft area on outburst, guiding action mechanism investigated. This study concludes that amount experiments group with local existence are relatively lower. (3.8035 kg) relative intensity (21.02%) GR5# were both lower than GN6# control group. However, could be migrated a long distance, maximum throwing distances three all over 16.73 m,...
