In addition it provides significant amount of corps like rice, tea, olive. Considering this facts, environmental protection of this area must be priority for national government. However waste management instruction have been ratified in Iran, there isn’t any specific...

Recently, by observing Algerian market, we find that the Chinese products are cornering this market. Since the living standards have risen in Algeria, as well, the purchasing power has increased too. Therefore, this led to the increasing amounts of municipal solid waste in Algeria. And it reached 10 million tons in 2011 and it is projected to reach 18 million tons by 2030. In Algeria, most of w...

In this paper, the Guangxi’s red mud disposal field is taken as the study area. Appropriate calculating parameters and boundary conditions were selected based on the survey data to build a Mohr-Coul0mb and fluid model under the plane-strain condition. FLAC software was adopted to simulate the distribution of pore water pressure, filtrate seepage paths, and leakage of the dam body under conditio...

The failure of a tailing dam occurs due to damage to the particles’ micro-structure. Understanding the deformation characteristics of the particle’ micro-structure is important for understanding the mechanics of instability in tailing dams. In our study, a series of experiments was conducted using a testing apparatus for micro-mechanics and the deformation of tailings from the Huangcaoping tail...
