Applied a novel machine learning algorithm-least squares support vector machines(LSSVM) into coal washery daily water consumption times series prediction.

Equal-dimension and new information SVR forecasting model of urban daily water consumption;

A nonlinear combined regression model for predicting daily water consumption was developed by introducing history data of daily water consumption in time series into regression analysis model using temperature and other parameters as variables.

The nonparametric multi regression model of urban daily water demand;

According to the effecting factor and the characteristic of urban daily water and the error of line model,we set up the nonparametrie multi regressive model of daily water demand.

The screening workshop,breaking preparement workshop,drying workshop are the place of dust concentrating in the preparation plant.

The application in many preparation plants has proved the noticeable economic and social benefits it can obtain.

The paper introduces it use such methods as capture noise abatement, acoustic septum, acoustic enclosure, damping vibration attenuation, wall noise reduction by absorption and etc for the main preparation plant workshops of the scond lining Coal Mine.

Research and practice of process for slime water treatment at a coal preparation plant;

Discussion on electric energy conservation in design of a coal preparation plant;

Probing into technological design of crushing classification jigging coal washing in Hongyang coal preparation plant;

Through analyzing various interferences occurring in the PLC monitoring system in the coal washery, this paper expounds the serous consequences probably caused by various interferences in the PLC monitoring system of the coal washery, and puts forward some concrete anti-interference measures.

In the light of the features of the production of the coal washery,and from the design thought,structure and function set-up of the collective and distributive monitoring system,this paper introduces a set of collective and distributive monitoring system of the coal washery composed of the industrial controller,PLC,and touching screen,etc.

Connecting with the practical application of electricity economizer in a certain coal washery, this paper sums up the experiences and results of applying this system electricity economizer.
