我国石灰石原料资源十分丰富,地区分布也很广,为冶金工业的发展提供了良好的条件。但是,石灰石矿床由于受含碳酸的浸蚀性水的溶蚀而形成了溶洞或裂隙,有的溶洞、裂隙为沉积物(如砂、土、砾石等)所充填。据调查,武钢乌龙泉石灰石矿矿体平均裂隙率8.31％,含泥裂隙率53.95％,则矿体裂隙含泥率为4.48％,采矿含泥率为0.41～7.5％。攀钢把关河石灰石矿矿体裂隙率10％,含泥裂隙率7～8.25％,泥土成分单一。江苏船山石灰石矿矿体裂隙率
China’s limestone raw material resources are very rich, the region is also very wide distribution, for the development of metallurgical industry provides a good condition. However, limestone deposits form karst caves or fissures due to erosion by carbonated, aggressive water, and some caves and fissures are filled with sediments such as sand, earth, gravel, and the like. According to the survey, the average fracture rate of ore body of Wulong Wulongquan limestone ore body is 8.31% and the clay-containing fracture rate is 53.95%. The ore-body fracture mud content is 4.48% and the mining mud content is 0.41-7.5%. Pangang Guanhe limestone ore body fracture rate of 10%, mud fracture rate of 7 ~ 8.25%, a single component of soil. Fracture rate of limestone ore body in Chuan Shan, Jiangsu Province
