The effect of cattle manure and slurry application on percolation and survival of Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium was investigated for different soil depths after the addition of water. Four treatments were chosen for the first set of experiments: (i) addition of inoculated farmyard manure on the soil surface, (ii) mixing of inoculated farmyard manure with t...

Dewatering of water-coal slurry or thickened product under conditions operating SUEK-Kuzbass JSC enrichment plants is a promising direction obtaining technogenic mineral resources. It should also be noted that the quality obtained will directly influenced by initial raw materials. If content carbon particles high and average ash solid phase low, such interest in terms additional volumes coal af...

To solve the problem of a rapid attenuation gas concentration along with drainage borehole collapse in tectonic coalbeds South China, constant pressure grouting technology inorganic, noncondensable material was proposed. Firstly, slurry fluidity, water separation rate, and sealing performance inorganic materials were tested under different water-cement ratios. The seepage model layer-through bu...

Ceramic waste is most commonly produce from ceramic industry, this waste is in the form of pest and hard form, pest waste is known as the filter waste or slurry waste, which is produced at the end of polishing and finishing of ceramic tiles. The paper discuss that ceramic slurry waste powder is replaced by cement in concrete. Concrete grade M25 was made by replacing by 0% to 30% of Ordinary Por...

The quality of borehole sealing is a key factor affecting the efficiency gas production. A new water-rich grouting material (RW) with composite coagulant and other additives was prepared in this study to overcome disadvantages long setting time low stone rate traditional cement materials. When coagulants 4 g B 2 g, RW reduced by 60.85% 50.62%, which significantly shortened material, respectivel...

A simple thermodynamic analysis suggests that oil can spontaneously displace water from coal’s surface if the coal particle has a water contact angle greater than 90°. However, the clean coal products obtained from laboratory-scale dewatering-by-displacement (DbD) test work assayed moistures substantially higher than expected. These high moisture contents were attributed to the formation of wat...

Investigations were carried out on coal tailings by conventional cell and column flotation techniques. Tests were conducted to assess processing coal tailings of Alborz Markazi coal washing plant in Iran by column flotation. The effects of reagent type/dosage were investigated with conventional flotation and their results were used in the performance of column flotation. Also the effects of the...
