Abstract
The invention discloses a slurry soil-to-water ratio calculating method, comprising the following steps of: firstly, collecting solute and solution samples; then, measuring the densities of the solute and solution samples for a plurality of times; and finally, calculating a soil-to-water ratio of solution through a formula. According to the invention, a method of monitoring the soil-to-water ratio by a density meter on line is adopted, and thus the method is suitable for monitoring the soil-to-water ratio of coal mine slurry. The densities of the solute (such as soil, fly ash and sand) and the solutions are sampled and converted by the formula to realize the solution soil-to-water ratio measurement. The solution density is measured by the density meter; the solutions are deposited under natural conditions; and the results of the deposition for multiple times are measured to deduce a soil-to-water ratio calculating method. The method is mainly applied to detecting the soil-to-water ratio of the grouting slurry under a coal mine; and the method has reliable use performance and can be used for improving the working efficiency.
Description
Technical field
The present invention relates to the detection method of grouting slurries under a kind of coal mine, the Tu Shui ratio of grouting slurries carries out detection method under particularly a kind of coal mine.
Background technology
Monitoring for the Tu Shui ratio of the grouting slurries under the China's coal-mine; Still be in the mode of manual detection, automatically the present domestic blank that is in of monitoring, grouting field at present in the colliery; To environment for use special under the coal mine; Often use manual work to fetch earth or machinery fetches earth,, wash away the mixing pulping through waterpower (hydraulic giant) with soil loosening.Should set up stock tank during slurrying, with loess add water in stock tank, stir into behind the homogeneous slurry can input well under.Stock tank should be established more than 2, makes grouting for one, and another carries out stirring pulping, is used alternatingly.The volume of stock tank should be able to guarantee the requirement of grouting amount.Also can solute be transported to the grass mixing plant, add water with special churn and stir pulping or after stirring pulping, directly get into grout pipe line with hydraulic giant.Perhaps can after the deposition dehydration, stir pulping and get into grout pipe line.
Slurry flow and Tu Shui ratio needs to measure during the slip casting, during slip casting, whenever also need measure the flow and the Tu Shui ratio of slurries for the parameter of obtaining slurries, just can better control the slurries of formation.
Therefore be badly in need of a kind of computing method of slurries Tu Shui ratio.
Summary of the invention
In view of this, technical matters to be solved by this invention provides a kind of computing method of slurries Tu Shui ratio.
