Tectonic phenomena in a various manner have an influence on mining processes. Among other things, they determine the position of the mining regions and mine fields. In the potash and mineral salt mining, in the choice and construction of the mining
method and the manner of the dead and the development work, in the influence of the tectonics must be taken into the consideration. For the estimation of the mining safety also the knowledge about the fracture tectonics developed in the planned mining

In the G. D. R. the share of open-cast mining production in the total mining production is 93 per cent. From this, about 60 percent account for brown-coal production. The article deals with problems of areal requirements, growing volumes of rubbish
, ground-water lowering, and the management of post-mining landscapes. - (IH)

The karst region of southeastern Missouri, which contains North America's largest springs and a rich biota, has its natural attributes threatened by mineral leasing for lead mines whose tailings pollute water. A classic environemntal conflict
Topoedaphic unit analysis: a site classification system for reclaimed mined lands
The aim of this paper is to outline a land classification system for reclaimed mined lands based on the use of topoedaphic units. The AA. describe the statistical methods used to delineate topoedaphic units and the discriminant model developed
for topoedaphic unit classification. They use data from the Glenharold Mine, North Dakota, USA.

River adjustment to changes in sediment load : the effects of tin mining on the Ringarooma River, Tasmania, 1875-1984
This paper is concerned with the impact of hydraulic tin mining on the Ringarooma River. It has two main aims : 1) to establish the transport history of the introduced debris over more than a century| and 2) to analyse the response of the river
to a sediment input which was particularly variable in time and space. Although mining has now virtually ceased, it will continue to have an impact on the physical landscape well into the twenty-first century.
