Microbial induced carbonate precipitation (MICP) is a new geotechnical engineering technology used to strengthen soils and other materials. Although it considered be environmentally friendly, there lack of quantitative data objective evaluation support conclusions about its environmental impact. In this paper, the energy consumption carbon emissions MICP are quantitatively analyzed by using life cycle assessment (LCA) method. The effects evaluated from perspectives resource results show that...
Backfill mining technology is the practice of returning waste materials underground for both disposal and geotechnical stability, however, a challenge with current technologies that they commonly require cement-based binders which have relatively high environmental impact. Finding alternatives to can improve performance this paper proposes microbial grouted backfill (MGB) as potential solution. In paper, effects cementation solution concentration (CSC), volume ratio bacterial (VRBC),...
Microbial induced carbonate precipitation (MICP) has the potential to have less hazardous impacts on environment compared with traditional reinforcement technologies. In this paper, mechanical property and cementing mechanism of MICP-treated mortar (MTM) are studied, double-layer rigid soaking mold is invented prepare high-strength MTM samples. The effects cementation solution concentration (CSC), ratio urea calcium chloride (CRUC), aggregate particle size, time properties researched....
We analyze a broad class of stationary solutions with residual N=1 supersymmetry four-dimensional N=2 supergravity theories terms quadratic in the Weyl tensor. These are encoded holomorphic function, which determines most relevant part action and plays central role our analysis. The include extremal black holes rotating field configurations, may have multiple centers. prove that they expressed harmonic functions associated electric magnetic charges carried by proper generalization so-called...
When cemented backfill mixture (CBM) is transported through pipelines from a plant to stopes, it experiences shearing forces over the transport time. In this paper, effects of solids concentration, binder content, shear rate and curing time on time-dependent rheological behaviour CBM were studied. It was found that long periods at constant greater than 5 s−1, stress decreased first then increased gradually with less 0.5 slightly firstly time, started behave similar test higher whose...
A novel and environmental-friendly backfill mining method known as upward slicing longwall-roadway cemented (USLCB) technology has recently been proposed successfully applied in mines extracting extra-thick coal seams located under sensitive areas. This paper studies the effects USLCB had on roof movement failure behavior using mechanical analysis approach. The application of Gonggeyingzi Mine is taken a case study with being monitored over single cycle, well multiple cycles different...
We present a class of static supersymmetric multi-center black hole solutions arising in four-dimensional N=2 supergravity theories with terms quadratic the Weyl tensor. also comment on possible corrections to metric moduli space these holes solutions.
