摘要
从岩体的岩性、时代、产状等方面，论证了八宝山煤矿北部的正长斑岩体为一岩盖，下部找煤前景可观，可在井下实施巷探和定向钻探找煤。
The rock mass of syenite porphyry in the north part of Babaoshan coal mine was demonstrated on its lithologic characters,geologic age and occurence.This rock mass was thought as a rock cap,under which existed prospect for search after coal.It is possible to conduct exploration and controlled drilling in underground roadway for search after coal and extending the service life on mine.
