Time-space coordination of mining operations for protection of the surface. [Poland]

Journal Article:

Abstract

In Polish mines, more than 41 percent of coal resources beneath built-up areas can be extracted. In 1973 an analysis of the mining and geological conditions was conducted in one of the mines, principally from the point of view of suitably coordinated mining advance with caving. Various possible systems of extraction were analyzed for three time periods up to 1985. A detailed inventory was prepared of surface structures in the whole concession area, particular attention being paid to industrial and social or communal areas. Preliminary and final predictions were made of deformation indices for various time periods, including predicted subsidences, and dynamic and static horizontal strains. The optimum variant was chosen, and capital expenditure and economic effects were taken into account. Solutions worked out for various sectors of the overall problem were presented to the mine management in the form of programmes for advancing the mining face in individual panels and seams so as to obtain maximum possible production with roof caving, under protected buildings.
