摘要
甘肃省金塔县穿山驯南白云岩已完成补充地质详查,开采在即,评价其可采性,意义重大。本文通过搜集相关文献,研判地质资料,从矿体地质特征、矿石加工技术性能、矿床开采技术条件三个方面,对其可开采性进行评价。与国内同类型矿山比较,矿山指标较好。在14条矿体中,以5号矿体和4号矿体规模较大,控制程度最高,可以作为主要矿体。采用“穿孔-涨裂-二次破碎-铲装-运输-破碎”采矿工艺,拟定条件下,矿山开采,经济效益和社会效益较好。
The detailed geological survey of Southern Chuanshanxun dolomite in Jinta County,Gansu Province has been completed,and mining is imminent.Evaluating its feasibility is of great significance.The paper collects relevant literature,analyzes geological data,and evaluates the mineability of ore bodies from three aspects:geological characteristics,ore processing technology performance,and mining technology conditions.Compared with similar mines in China,the mine indicators are better.Among the 14 ore bodies,the 5#and 4#ore bodies are larger in scale and have the highest degree of control,making them as the main ore bodies.The mining process of“perforation-expansion cracking-secondary crushing-shovel loadingtransportation-crushing”is adopted,and under the proposed conditions,the economic and social benefits of mining are good.
