在胶东半岛西北部,渤海湾南岸的龙口市境内,我国第一座海滨矿区——龙口矿区正在迅速崛起。龙口矿区横跨龙口、蓬莱两地,陆地面积东西长28km,南北宽12～15km,总面积为350km~2,陆地煤炭储量13.9亿t,海底煤炭储量13.1亿t。煤田为下第三系褐煤,可采煤层总厚度为1.23～15.6m。褐煤发热量为16～19MJ/kg,油页岩发热量为14～15MJ/kg,含油率平均为14.31％。可做动力、民用燃料、化工和化肥生产用煤。龙口煤田1968年破土兴建,已经历了21个年头。
In the northwest of Jiaodong Peninsula and Longkou City on the south bank of Bohai Bay, the first coastal mining area in our country, Longkou Mining Area, is rapidly emerging. Longkou mining area across Longkou, Penglai two land area of 28km east-west, north-south width of 12 ~ 15km, with a total area of 350km ~ 2, land coal reserves of 1.39 billion t, seabed coal reserves of 1.31 billion t. The coal field is the Tertiary lignite with a total thickness of 1.23 ~ 15.6m. Lignite heat 16 ~ 19MJ / kg, oil shale heat is 14 ~ 15MJ / kg, the average oil content was 14.31%. Can do power, civil fuels, chemical and fertilizer production of coal. Longkou coalfield broke ground in 1968, has experienced 21 years.
