摘要：为保证某金矿充填系统的可靠运行,对全尾砂的自然沉降特性开展试验研究。结果表明,该金矿全尾砂在0~45min时段,沉降速度较慢,然后逐渐加快,24h后最大沉降质量分数和沉降容重分别达到59.1%和15.89kN/m^3。将该全尾砂用于充填工程时,需充分考虑其沉降特性及参数,以满足充填生产的需求。
Tests were conducted on the natural settling proper- ties of full tailings to ensure the reliable operation of the filling system in a gold mine. The results showed that settling speed for the gold full tailings was slow in the period of 0- 45 rain. and then gradually accelerates. After 24 hrs the maximum settlement concentration and settlement volume weight could reach 59.1% and 15.89 kN/m^3 respectively. In filling engineering operation by the full tailings, it is necessary to consider its settlement character so as to meet the demands of the production.
