Mechanical and physical properties of chalk and impacts on mining operations and slope designs

摘要

Chalk occurs in northern Europe from the southern UK to eastwards deep into Russia.It is exploited as an industrial mineral for a large variety of uses. From the examples of threedifferent chalk mining operations, it is shown that although geologically and geochemicallyquite similar, all three deposits have very different physical and geomechanical properties whichin turn have impacts on slope designs as well as mining methods, mine planning and equipment selection.
