Ground vibration is an integral part of the rock blasting process in surface mines, which may cause severe damages to structures and plants in the nearby environment. Therefore, its prediction plays an important role in the minimization of environmental impacts. The peak particle velocity (PPV) is an important predictor for ground vibration.

Nevada Bureau of Mines and Geology. University of Nevada Reno .

Characteristics of subsidence by mining activities. Figure 3a and b show the frequency of subsidence as a function of the dip angle and thickness of the coal bed, respectively. In Fig. 3a, the dip angle of the coal bed is 48.9° on average, which is greater than the average dip angle of coal beds in South Korea. The thickness of the coal bed at which the subsidence …

By the early 1900s mining activity in the state was so widespread that the Oregon Bureau of Mines and Geology 1916 Handbook of Mines was over 300 pages long and listed several hundred mines and prospects in nearly 75 districts.

MINING IN IRAN. ii. MINERAL INDUSTRIES. Iran is rich in mineral resources, but until recent times no systematic geological survey and inventory was made to determine the extent and quality of its mineral wealth. For example, the occurrence of chromite in Iran was only determined in 1940, and the enormous copper reserves at Sar-Čašma only in 1967.

Iron mining ceased at Sunrise in 1980 and at South Pass in 1983, although both mines still host significant iron resources. Industrial minerals such as bentonite (first described in Wyoming), gypsum, aggregate, crushed stone, chemical-grade limestone, decorative stone, and trona, play a continuing role in the state's economy.
