Migration characteristics of heavy metals in the

Lanmuchang mercury-thallium mine, a typical polymetallic mine is located in southwestern Guizhou, China, is the most serious and typical area resulted from multi-metal contamination (Tl, Hg, As, and Sb).

Selection of suitable engineering modes for CBM

2016-11-1  In western Guizhou, the coal seams in alternate with sandstone and mudstone in the coal-bearing strata,and certain peaks in the gas logging data indicate that the sandstone corresponds to a gas layer at the CBM well site (e.g., at depths between 570.40 and 611.11 m in Fig. 12). Such layers may have potential for natural gas (including CBM

Geological Analysis of Nianfa Coal Mine Project at Shatan

mining is a high risk work[3-4], so the project geological analysis of coal mine is a necessary work. Guizhou province is rich in coal mine, so this paper has analyzed geological conditions of Nianfa coal mine project at Shatan, Huairen city, Guizhou province, and gives guidance to coal mining

Migration characteristics of heavy metals in the

After the mercury-thallium mining, a large area of surrounding rocks such as argillaceous sandstone with high contents of Tl, Hg, As, and Sb is exposed to air. Weathering caused the argillaceous sandstone to form different weathering layers, including the grey-black external layer, the brown-yellow middle layer and the gray-white inner layer

Discrete element modeling of a mining-induced rock slide

2017-8-25  Mining-induced landslide is a man-made geohazard that has drawn increasing public attention. Studies have shown that these landslides are generally triggered by a conflu- landslide in Guizhou Province, China as a case study to investigate the failure mecha- namely sandstone strata, interbedding carbon shale, coal, and sandstone strata

Deformation monitoring and failure mode research of

2021-4-29  The Jianshanying landslide in Guizhou province, China, is a typical mining-induced landslide with its complex formation in karst mountainous area. However, the spatiotemporal deformation characteristics and failure mechanism are still unknown. In this paper, the surface deformation time series from 2017 to 2020 is firstly estimated by combining multi-temporal synthetic aperture radar (SAR
