我厂盐矿开采已有15年了,以开采浅部盐矿层(300到400米)为主。为了合理开采地下盐矿资源,经盐矿补充设计,通过审议和资源管理部门正式批准,于1984年对老采矿区进行了深部(800米左右)挖潜开采。根据湖北省云应地区盐矿资源管理规定,埋深800米左右的盐群(矿层)为首采层,是老采区进行挖潜补充设计的主要对象。第一对盐
I plant salt mining has been 15 years, the exploitation of shallow salt (300 to 400 meters) based. In order to reasonably exploit the underground salt resources, the deep mining (about 800 meters) tapping mining was carried out on the old mining area in 1984 through the additional design of salt mines and the formal approval of the resource management department. According to the regulations of salt mineral resources management in Yunying area of Hubei Province, salt group (ore layer) with a buried depth of about 800 meters is the first mining layer, which is the main target for tapping potential in the old mining area. The first pair of salt
