The conventional flotation process of CGFS has the bottlenecks of low carbon recovery and high collector dosage. In order to address these issues, CGFS sample taken from Shaanxi, China was used as the study object in this paper. A new process of size classification − fine grain ultrasonic pretreatment flotation (SC-FGUF) was proposed and its separation effect was compared with that of whole-grain flotation (WGF) as well as size classification − fine grain flotation (SC-FGF). The mechanism of its enhanced separation effect was revealed through flotation kinetic fitting, flotation flow foam layer stability, particle size composition, surface morphology, pore structure, and surface chemical property analysis. The results showed that compared with WGF, pre-classification could reduce the collector dosage by 84.09% and the combination of pre-classification and ultrasonic pretreatment could increase the combustible recovery by 17.29% and up to 93.46%. The SC-FGUF process allows the ineffective adsorption of coarse residual carbon to collector during flotation stage to be reduced by pre-classification, and the tightly embedded state of fine CGFS particles is disrupted and surface oxidizing functional group occupancy was reduced by ultrasonic pretreatment, thus carbon and ash is easier to be separated in the flotation process. In addition, some of the residual carbon particles were broken down to smaller sizes in the ultrasonic pretreatment, which led to an increase in the stability of flotation flow foam layer and a decrease in the probability of detachment of residual carbon particles from the bubbles. Therefore, SC-FGUF could increase the residual carbon recovery and reduce the flotation collector dosage, which is an innovative method for carbon-ash separation of CGFS with good application prospect.</p></div>","PeriodicalId":48625,"journal":{"name":"International Journal of Mining Science and Technology","volume":"34 6","pages":"Pages 867-880"},"PeriodicalIF":11.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2095268624000673/pdfft?md5=952a4af4dfdd7a8f2d505d013c8ac6bd&pid=1-s2.0-S2095268624000673-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141849931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While some production data analysis techniques have been adapted from conventional oil and gas wells, there remains a gap in the understanding of pore pressure generation and evolution, particularly in wells subjected to large-scale hydraulic fracturing. To address this gap, a novel technique called excess pore pressure analysis (EPPA) has been introduced to the coal seam gas industry for the first time to our knowledge, which employs dual-phase flow principles based on consolidation theory. This technique focuses on the generation and dissipation for excess pore-water pressure (EPWP) and excess pore-gas pressure (EPGP) in stimulated deep coal reservoirs. Equations have been developed respectively and numerical solutions have been provided using the finite element method (FEM). Application of this model to a representative field example reveals that excess pore pressure arises from rapid loading, with overburden weight transferred under undrained condition due to intense hydraulic fracturing, which significantly redistributes the weight-bearing role from the solid coal structure to the injected fluid and liberated gas within artificial pores over a brief timespan. Furthermore, field application indicates that the dissipation of EPWP and EPGP can be actually considered as the process of well production, where methane and water are extracted from deep coalbed methane wells, leading to consolidation for the artificial reservoirs. Moreover, history matching results demonstrate that the excess-pressure model established in this study provides a better explanation for the declining trends observed in both gas and water production curves, compared to conventional practices in coalbed methane reservoir engineering and petroleum engineering. This research not only enhances the understanding of DCBM reservoir behavior but also offers insights applicable to production analysis in other unconventional resources reliant on hydraulic fracturing.</p></div>","PeriodicalId":48625,"journal":{"name":"International Journal of Mining Science and Technology","volume":"34 6","pages":"Pages 763-781"},"PeriodicalIF":11.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2095268624000843/pdfft?md5=3530459fadc94ae26221e14fec5d6ef5&pid=1-s2.0-S2095268624000843-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141841325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The conventional Sadowski formula mainly focuses on blast center distance but neglects the amplification effect of blasting vibration waves by terraced terrain, from which the calculated blasting vibration velocities are smaller than the actual values, affecting the safety of the project. To address this issue, our model introduces the influences of slope and time into Sadowski formula to measure safety through blast vibration displacement. In the northern section of the open-pit quartz mine in Jinchang City, Gansu Province, China, the data of a continuous blasting slope project are referred to. Our findings reveal a noticeable vibration amplification effect during blasting when a multi-stage slope platform undergoes a sudden cross-sectional change near the upper overhanging surface. The amplification vibration coefficient increases with height, while vibration waves within rocks decrease from bottom to top. Conversely, platforms without distinct cross-sectional changes exhibit no pronounced amplification during blasting. In addition, the vibration intensity decreases with distance as the rock height difference change propagates. The results obtained by the proposed blast vibration displacement equation incorporating slope shape influence closely agree with real-world scenarios. According to Pearson correlation coefficient (PPMCC) analysis, the average accuracy rate of our model is 88.84%, which exceeds the conventional Sadowski formula (46.92%).</p></div>","PeriodicalId":48625,"journal":{"name":"International Journal of Mining Science and Technology","volume":"34 5","pages":"Pages 631-641"},"PeriodicalIF":11.7,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2095268624000685/pdfft?md5=0027b3f8c5d79cad0190a5014dec61a2&pid=1-s2.0-S2095268624000685-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141714756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The field-scale pillar models (width-to-height, W/H=1, 2 and 3) were calibrated based on the empirically predicted stress-strain curves of Creighton mine pillars. The results indicated that as the W/H ratios increased, the VGBBM effectively predicted the transition from strain-softening to pseudo-ductile behavior in pillars, and explicitly captured the separated rock slabs and the V-shaped damage zones on both sides of pillars and conjugate shear bands in core zones of pillars. The volumetric strain field revealed significant compressional deformation in core zones of pillars. While the peak strains of W/H=1 and 2 pillars were relatively consistent, there were significant differences in the strain energy storage and release mechanism. W/H was the primary factor influencing the deformation and strain energy in the pillar core. The friction coefficient of the structural plane was also an important factor affecting the pillar strength and the weakest discontinuity angle.
