Characteristics of two formulations of trifluralin, an emulsifiable concentrate (EC) and emulsion, oil in water (EW), the latter being a new formulation of our design, were investigated and compared. Attention was focused on particle size distribution and aspects of the two aqueous dilute formulations as the most characteristic and comparable parameters. The results show that the trifluralin EW formulation has certain advantages over the EC formulation, but a final estimate will be possible only after testing biological efficacy of the new formulation (EW).

Water and sand inrush is one of the most serious threats in some shallow coal mines in China. In order to understand the process of sand inrush, experiments were performed to obtain the criterion for sand inrush. First, seepage tests were carried out to study the hydraulic properties of granular sandstone. The results indicate that seepage velocity has a linear relation with the porosity and particle-size distribution parameter. Then, sand inrush tests were conducted to investigate the critical conditions for sand inrush occurrence. It is determined that the sand inrush zone can be clearly distinguished based on the values of porosity and particle-size distribution parameter. Additionally, sand inrush tended to happen in the conditions of high porosity, high seepage velocity, and large particle-size distribution parameter. Further, general principles for preventing the water and sand inrush were proposed, such as reducing the porosity, improving the pore structure, and decreasing the seepage velocity. The proposed principles have been successfully used in situ to control the water and sand inrush.

Basic Properties

Compared with natural gypsum, the basic properties of FGD gypsum are studied based on the test results and then the influence of FGD gypsum’s chemical constituents, impurities and particle size distribution on its products is analyzed. The results indicate the impurities play an important role on the FGD gypsum behavior. Finally, the differences between FGD gypsum and natural gypsum are summarized.
