Influence of large-diameter advanced boreholes on deformations of a coal shelf seam
Authors:
Abstract
Sudden emissions of coal and gas in cleaning faces of single seams of Donetsk basin are currently prevented by drilling of advanced wells of large diameter. About 30% of faces of all emission-hazardous seams of the central region of Donbass are developed with application of drilling of advance wells as protective measures. The schemes of wells location relative to the cleaning face are different, and the frequency of their location excludes emissions. As is known, the mining pressure and the pressure of the gas contained in the coal are the main factors determining the occurrence and flow of the release ...
