摘要:
遂昌金矿采矿方法变更为充填采矿法，其关键在于充填工艺与充填系统，对于不同的充填骨料，其物理力学性质、矿物与化学成分各不相同，充填管道输送性能及作为充填材料的力学性能差别较大。通过对不同来源的骨料进行试验研究、理论分析和方案对比，获得矿山易于获取的充填骨料的浓缩脱水、充填配比等关键技术参数，进而对其作为充填骨料的性能进行科学评价，最终确定铅锌矿尾砂及花岗岩岩粉作为充填骨料的可行性及具体配比参数。

Abstract:
The transition to the filling mining method at Suichang Gold Mine hinges on the filling process and system. The physical and mechanical properties, mineral composition, and chemical composition of various filling aggregates differ significantly, leading to notable variations in pipeline transport performance and mechanical properties as filling materials. This study conducts experimental research, theoretical analysis, and comparative evaluations on aggregates from different sources. Key technical parameters, including thickening and dewatering, and filling mix ratios, were determined for aggregates readily available at the mine. The findings scientifically evaluate the performance of these materials as filling aggregates, ultimately confirming the feasibility and specific mix ratios of lead-zinc tailings and granite powder as filling materials.
