The Influence of Engineering-Geological Conditions on the Construction of the Radioactive Waste Dump [PDF]
Acta Montanistica Slovaca, 2007 A secure stability and reliable serviceability of the radioactive dump is a difficult engineering problem. Due to the difficult geological formations determined mainly by a high compressibility, the low shear strength of soils, and the high ground water ...

Deep Underground Science and Engineering, EarlyView.This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Problems of definitive slopes mining at Doly Nástup Tušimice [PDF]
Acta Montanistica Slovaca, 2007 The instability of slopes influents mining business in many aspects at opencast mining. The temporary decrease of intended mined volumes due to landslips is common and sometimes there is necessary to change origin-mining plans.

Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).
