老厂弯子街矿是以锡、铜、铅为主的多金属地下矿山。矿床类型多,从上到下是砂锡矿床、含锡褐铁矿网状矿型矿床、层间氧化矿床、接触带矽卡岩硫化矿床、电气石细脉带矿床,在空间上贯穿其它类型矿床,称为“五层云”。地表砂锡矿床和深部硫化矿床,勘探程度较高。但对形态多样、构造复杂、多层产出、规模较小的层间氧化矿体,即矿山当前生产的主要矿体,却控制不够。 Old factory bend street mine is tin, copper, lead-based multi-metal underground mine. There are many types of deposits, including sand-tin deposit, tin-limonite reticular ore deposit, interlayer oxidation deposit, contact zone skarn sulfide deposit and tourmaline vein belt deposit from top to bottom, which spatially run through other types Deposit, known as the “five-story cloud.” Surface sand tin and deep sulfide deposits, a higher degree of exploration. However, there are not enough control over the intergranular oxide orebodies that are diverse in shape, complex in structure, multi-layered in output and small in scale, that is, the main orebodies currently produced in mines.
