The Optimization Of Deep Well Drainage System

Coal is China’s leading energy, the coal boss status does not happen a fundamental shift in the short run. Due to the exploitation of large area, for a long time, high strength, north China region and even the shallow coal seam coal has dried up, this has made it necessary for us to continue to increase the depth of the mine, to get enough coal to meet the needs of people. Mine drainage system is an important part in the production of coal mine, with the increase of depth of the mine, mine hydrogeological condition is more and more difficult to grasp, ensuring safe and reliable, efficient work of the drainage system for deep well is particularly important.Compared with shallow Wells, deep Wells drainage systems tend to be more large-scale equipment, such as high lift water pump, high power motor, large diameter high pressure valve, etc. At present, because of the skill level of each manufacturer has different, the materials used, causing them to produce equipment does not ensure that fully meet customer demand. For this reason, this article through to the equipment manufacturers a lot of practical research, analysis and research, summarized out some easy drainage equipment selection and optimization; Put forward the measures to improve the efficiency of deep well drainage pipe network; At the same time, in view of the mine water inrush, water hammer force problem and water pump room ventilation and cooling are discussed in this paper, gives the prevention countermeasure and the method to solve the problem. In view of the existing drainage facilities computer-aided selection of the defects in the software, using Microsoft Visual Studio 2010 software development tools and SQL Server 2008 database development tools, developed a "deep well drainage equipment selection system" software, and use the software to complete the hebei type selection design of mine drainage equipment, at the same time, aiming at the particularity of deep well drainage system, the reasonable selection and system configuration of drainage equipment, for safe and reliable operation of the mine drainage system to lay a good foundation.
