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.
