For those karst voids with infill and that were smaller than 4 m, the roofs of the voids were drilled through and artificial construction materials (cement, sodium silicate, crushed stone, and red clay) were deposited, mixed, and compacted in the voids (e.g., 24, 29, and 33 m deep in scenario 1 and 25, 31, and 33 m deep in scenario 2).

Potential Environmental Impacts of Quarrying Stone in Karst. The influence of quarry size on environmental impact is obvious: all other things being equal, the larger the quarry, the larger the geomorphic impact. The size of quarries has increased over time, and so has their impact. (pg 8) Poorly designed or poorly controlled blasts may cause ...
Oct 31, 2018 Located in Fangshan District, Stone Flower Cave, also known as Shihua Cave or Shihuadong Cave, is a national famous scenic spot and geological park which is noted for the unique Karst cave sightseeing and a valuable informational bank on geological research. Originally it was called Qianzhen or Shifo Cave, names given it by the wanderer monk Yuan Guang during the Ming Dynasty …
Our stone paper holds a C2C Cradle to Cradle Silver Certification. That means if you do have to dispose of your Karst notebook, have no fear; they are 100% recyclable. We recommend putting them in your Type 2 stream. If any errant pages ended up in landfill (something to avoid but it happens), they will degrade in the sun within 12 months.
World Heritage Caves and Karst: A Thematic Study 2 1.3 Definitions Karst Landscapes The word karst can be traced back to pre-Indoeuropean origins (Gams 1973, 1991, 2003; Kranjc 2001). It stems from karra/gara meaning stone, and its derivatives are found in many languages of Europe and the Middle East. A stony limestone region known as Kras (later germanicised to Karst)

between limestone and open karst voids causes strong reflections. This work shows a series of 2D and 3D GPR surveys for karst void mapping within a pillar in a stone mine and also below the floor of mine tunnels. In this mine, karst voids are very dangerous and the miners spend significant time and resources to ensure the tunnels walls are stable.
Oct 22, 2019 Karst landscapes, representing approximately 13% of the world’s land surface, are mostly formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum (Chen et al. 2017). Rocky desertification, a process of land degradation, poses a potential threat to the environment and ecosystem in karst areas (Yuan 1997).
Jan 10, 2021 Structure and assembly processes of soil bacterial communities under different land use at karst areas remained poorly understood to date. To address this issue, soil samples from arable land and pristine forest over a karst cave, located in the acid rain impacted area, Hubei province, were collected and subjected to high-throughput sequencing and multivariate statistical analysis.
Apr 30, 2020 The dissolution features of karst foundations at different depths must be clearly identified before taking proper karst treatment measures. In this paper, more than 200 engineering data samples are collected from typical carbonate karstic regions in southwestern China, and 12 most representative engineering site were picked out.
