In the light of the waterlogging forming reasons in the built area and combined with the areal drainage conditions, the planning is considered to adopt the principle of high water level and high-speed drainage, low water level and low-speed drainage, and waterlogging water pumping and drainage for prevention.

In the mine drainage system many drainage pumps must work correspondly.

This design basis of the provided by the bureau surveying place normal and the largest yield,by "Coal Mine Safety Regulations" and the design specification,atter a scientific calculation and analysis,carry on the choice in view of the drainage pump and the discharge pipe to calculate and to verify.

Design of computer control and measurement system for coal mining main drainage pump;

In accordance with the characteristics of main drainage pump for coal mine and the present development of control and measurement technology, the paper introduces a kind of modularized computer monitoring system for main drainage pump underground coal mine.
