Summary:This method employs the technics when tunnels are developed near to the deposit at several sites and towards several directions, cut the drilling grottos. New type drilling machine makes use of grotto as drilling support to drill to wards the deposit. Gas mineral is drawn from the upper part over the deposit and liquid mineral is drained out from the lower part of the deposit. It is under better conditions of ground-temperature. The minerals are sent out through pipeline conveying systems. After all the fluid minerals have been drawn out, the mining of oil-impregnated solid deposit would be carried on.
