阐述了金川有色公司二矿区大面积下向机采盘区细砂充填中利用废料充填的意义，废料堆放原则和采取的技术措施。为了使该工艺参数更科学合理，在八区六分层六号进路埋设了差动式电阻应变计和应力计，观测回采过程中应力变化。对观测资料的分析、计算和对数十条进路顶板、侧邦充填体的实际观察表明，水泥砂浆—废石充填工艺技术可行，能确保下向机采进路安全回采，社会效益和经济效益显著。
The paper expounds the significance of using waste filling in the fine sand filling of the large area down machine mining area of Jinchuan Nonferrous Co., Ltd., the principle of waste stacking and the technical measures taken. In order to make the process parameters more scientific and reasonable, differential resistance strain gauges and stress gauges are buried in No.6 six-storied sixth route to observe the stress changes in the process of recovery. The analysis and calculation of the observed data and the actual observation of dozens of ways of roofing and pavement filling indicate that the cement mortar - waste rock filling technology is feasible, which can ensure the safe recovery of the mining machine road, social benefit and economy Benefit significantly.
