自1981年起,法国铁矿石开采量日益减少,主要因洛林铁矿区产量下降所致。如1980年开采矿石2770万吨(910万吨金属),1981年只开采2050万吨(630万吨金属)。铁矿区包括几个矿床,长80公里,开采面积达10万公顷以上。该矿区由倾角4°以下的若干水平矿层组成。矿层厚2.5～8米,其东部露出地表,西部埋藏深达250～270米。矿床形状规则,断层少。
Since 1981, the amount of iron ore mining in France has been declining, mainly due to the decline in the output of the Lorelin iron ore area. For example, 27.7 million tonnes (9.1 million tonnes) of ore were mined in 1980 and 20.5 million tonnes (6.3 million tonnes) in 1981. Iron ore includes several deposits, 80 km long, mining area of 100,000 hectares or more. The mine consists of a number of horizontal beds below 4 ° dip. The ore thickness is 2.5 ~ 8 meters, the surface of which is exposed in the east and the depth of 250 ~ 270 meters in the west. Deposit shape rules, fault less.
