水文地质及其对会东矿西边坡的影响

水文地质是影响边坡稳定性的一个不可忽视的因素。为了给边坡稳定性研究提供足够的科学依据,对会东矿露天西边坡所在区域的气候条件、年降雨量分布与降雨量、山洪、上层滞水、风化裂隙潜水等水文情况作了详细调查,同时还对矿区的含水层、涌水点和涌水量作了全面勘察和测量。这些情况的获得,使采场边坡治理与防范措施的制定更具有现实性和针对性。

Underground mine stream crossing assessment: A multi-disciplinary approach

Underground mine designs typically try to avoid extraction beneath streams and rivers of any significant size, especially when the overburden rock thickness between the stream bed and the mine is thin.Potential issues with mining beneath streams include excessive groundwater inflow to the mine, weak ground(roof, floor, and pillar) conditions, horizontal stress effects, as well as stream loss and other potential adverse environmental effects. However, there are times when crossing beneath a stream or river is necessary to move into a new area of mineral reserve without creating additional mine access points from the ground surface. Often, stream crossings are completed without thorough assessment, potentially resulting in increased costs, decreased safety, and, in some cases, failure to advance the mine.Selection of the most favorable location(s) to cross the stream must account for numerous factors and the associated assessment often requires a multi-disciplinary approach. Stream crossing investigations often require geological, hydrogeological, geotechnical, and geophysical expertise. Phases of stream crossing investigations include desktop evaluation of maps and aerial photography, stream bed observations, drilling, detailed rock core logging, downhole geophysical surveying, hydraulic conductivity testing(packer testing), geotechnical laboratory testing, assessment, and reporting. The deliverables from a stream crossing assessment typically include geological, geotechnical, and hydrogeological characterization of potential stream crossing locations, classification of favorable and unfavorable crossing locations,recommendations for entry design and pillar sizing, and recommendations for if, and how, to conduct pre-grouting activities. Examples of technical aspects of data collection and assessment are provided based on decades of industry experience conducting stream crossing assessments in various underground mining scenarios.

Hydrogeochemistry: an investigation tool to evaluate infiltration into large moving rock masses (case study of La Clapière and Séchilienne alpine landslides)

Isotopic and hydrogeochemical methods have been used to investigate groundwater movement inside the La Clapière and Séchilienne alpine landslides in southern France. The δ¹⁸O data were used to determine the infiltration altitudes of the two areas. The infiltration results indicate that the landslides are recharged from beyond the landslides' perimeters. Hydrogeochemical data on major ions were collected from springs. Numerical simulations of water–rock interactions were then undertaken. The major petrographic contrast between the limited sedimentary rocks and the more common micagneiss/micaschist results in a marked change between the measured and calculated groundwater contents. This contrast of 800 mg/l of SO₄ in the Triassic rocks but only 100 mg/l for the waters from the metamorphic strata at La Clapière is significant. Two different groundwaters have been identified in both landslides: (1) a perched shallow saturated zone near the slope summit; and (2) a deep saturated zone located at the foot of the slope. Chemical monitoring of spring waters in the two zones has allowed an assessment of the infiltration within the slope over time. There is a good correlation between the sulphate content of the perched waters and rate of slope movement, with a sulphate dilution peak corresponding to an acceleration in the movement of the landslip. However, there is no correlation between the chemistry of the deep aquifer and the speed of movement. It would appear therefore that the hydromechanical behaviour of the landslide depends on the vertical leakage from the perched aquifer down to the basal aquifer and the near-surface effects of the water movement.
