攀枝花残坡积钛砂矿远景资源量预测

Prospective Prediction of Panzhihua Titanium Ore Reserves

攀西地区钛资源十分丰富,是理想的钛项目建设基地。目前原生矿床的利用已得到广泛重视,但对该区钛砂资源状况了解不深。通过用统计和曲线积分方法(并适当参考云南钛砂资源的资料)来确定调查区合理的钛砂矿边界品位,达到矿产资源的最优利用;以规则的取样投影图形代替水平投影,对传统的地质块段法储量估算进行了数学纠正以得到合理的估算参数,并对调查区钛砂资源进行了远景储量估算。通过调查,估算攀枝花地区钛砂334资源量约达336.177×104 t;并据地质和工程因素划分了三级远景预测区,为进一步勘查该区钛砂资源状况提供了参考。

Titanium resource of Panzhihua is extremely rich, and it is the ideal titanium project construction base. However, we know little about the titanium resources in the area at present. The titanium border grade of Panzhihua is identified by means of statistical and infinitesimal calculus （referring to the data of Yunan＇s titanium properly） to get optimum application. We adopt the rule sampling projection graphics in place of the level projection to estimate the traditional pieces of geological reserves, and get correct estimation parameters. The survey results show that Panzhihua titanium resources amount to about 336.177 million tons for sand 334. According to geological and engineering factors, there are the three prospective prediction areas, which provide a reference for further exploration.
