Surface Geophysical Methods for Detection of Underground Mine Workings
Efforts to delineate underground mine workings in the vicinity of tailings impoundments has relied on available maps and confirmatory boreholes. Often the characterization of regions between boreholes remains suspect or entirely unknown. Surface geophysical measurements can be used to supplement the borehole data and better delineate these intermediate zones. Furthermore, geophysics can be used...
متن کاملThe Introduction of Roof Bolting to U.s. Underground Coal Mines (1948-1960): a Cautionary Tale
Perhaps the most significant development in coal mine ground control during the last century was the introduction of roof bolting during the late 1940’s and 1950’s. From an engineering standpoint, roof bolts are inherently more effective than the wood timbers they replaced. Roof bolts promised to dramatically reduce the number of roof fall accidents, which then claimed hundreds of lives each ye...
متن کاملThe evolution of drill bit and chuck isolators to reduce roof bolting machine drilling noise
Among underground coal miners, hearing loss remains one of the most common occupational illnesses. To address this problem, the U.S. National Institute for Occupational Safety and Health Office of Mine Safety and Health Research (NIOSH OMSHR) conducts research to reduce the noise emission of underground coal mining equipment, an example of which is the roof bolting machine. Field studies show t...
متن کاملOptimization of Mine Support Parameters Using Neural Network Approach
Since ground control operation is an ‘imprecise’ area of engineering due to the fact that we are dealing with a material produced by nature (the ground). In many circumstances, our fundamental understanding of soil and rock behavior still falls short of being able to predict how the ground will behave. Cause-wise analysis of mine accidents reveals that roof falls continue to remain the single l...
متن کاملAn Analysis of the Possibility of Intersystem Transformations for Purposes of Geo-referencing Old Mine Workings
The paper is dedicated to the issues of both planar and spatial transformations with respect to the territory affected by mining activities. The planar transformations have been applied among the planar Otto mine coordinate system, St. Stephen Datum of Cadastre Coordinates, and the Datum of Uniform Trigonometric Cadastral Network (hereinafter referred to as JTSK). Here basic transformation char...
