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 a kind of underground coal mine grouting slurries, particularly a kind of Tu Shui ratio of underground coal mine grouting slurries carries out detection method.
Background technology
For the monitoring of the Tu Shui ratio of the grouting slurries under China's coal-mine, still be in the mode of manual detection, automatic monitoring is domestic is at present in blank, at present in grouting field, colliery, for the environment for use that underground coal mine is special, often use and manually to fetch earth or machinery fetches earth, by soil loosening, wash away mixing pulping through waterpower (hydraulic giant).Should stock tank be set up during slurrying, loess be added water under getting final product input well stir into homogeneous slurry in stock tank after.Stock tank should establish more than 2, and make grouting for one, another carries out stirring pulping, is used alternatingly.The volume of stock tank should be able to ensure the requirement of grouting amount.Also solute can be transported to grass mixing plant, add water with special churn and stir pulping or directly enter grout pipe line after stirring pulping with hydraulic giant punching.Or pulping can be stirred after precipitation dehydration and enter grout pipe line.
During slip casting, slurry flow and Tu Shui ratio need to measure, and during slip casting, the parameter often in order to obtain slurries also needs the flow and the Tu Shui ratio that measure slurries, just can better control the slurries formed.
Therefore a kind of computing method of slurry soil-to-water ratio are badly in need of.
Summary of the invention
In view of this, technical matters to be solved by this invention is to provide a kind of computing method of slurry soil-to-water ratio.
