【摘要】 为了处理西石门铁矿的尾矿，运用尾砂固结排放技术，将固结的尾矿排放到西石门铁矿的北区塌陷坑。通过理论分析、实验室试验、数值模拟、和小型工业试验等手段，研究了新型尾砂固结胶凝材料，分析了尾砂固结过程的机理，对尾砂固结体的稳定性也进行了研究，同时也阐述了尾砂浓缩-固结一体化技术，针对尾砂固结排放技术的应用也开展了研究。研究结果表明在西石门铁矿实施尾砂固结排放，在技术上是可行的，在经济上也是合理的，同时这种对尾矿的处理方式有利于环境保护和生态恢复。由此可以得出，尾砂固结排放技术的开发及应用，有助于促进尾矿处理技术的新发展，从而改变传统的利用尾矿库存放尾矿的方式，进而可以消除尾矿库的存在可能造成的环境污染及溃坝等安全隐患。更多还原

【Abstract】 In order to dispose the tailings of Xishimen iron mine, the technology ofemission of cemented tailings is applied, and the cemented tailings are discharged intothe collapse pit on the north part of Xishimen iron mine. By means of theoreticalanalysis, laboratory experiments, numerical simulation, and small-scale industrial test,the study on the new binding material for cementing tailings is conducted, and themechanism for the cementation of tailings is analized, the stability of cementedtailings structures is analized numerically as well. In addition, the technology ofintegrating concentration and cementation together is introduced, and the applicationof the emission of cemented tailings is also demonstrated. The research resultsillustrated that, applying the technology of emission of cemented tailings on disposingthe tailings of Xishimen iron mine, is technically feasible and economicallyreasonable. Besides, this treatment of tailings is beneficial to environmental protectionand ecological restoration. Therefore, the development and application of thistechnology is helpful to the development of techniques of handling tailings.Furthermore, this technology is able to change the traditional way of storing tailingsin tailings reservoir, which in turn can eliminate the environmental pollution as wellas the potential safety hazard of dam breakage caused by the tailings reservoir.更多还原
