Abstract: |
With the growth of the service life of mine and increasing of extending mining, underground operationrequires more and more new drilling field of gas drainage. The increase of the length of drainage pipecauses rising of the resistance of gas flow and changes the reasonable resistance distribution of the initialdrainage system, and it also affects the efficiency and reliability of gas drainage. In order to improve efficiencyand reliability of the gas drainage system, it is necessary to optimize the pipeline system of gas drainage.The author considers the pipeline system as a directed graph, and analyzes the flow resistance of pipelinewith the principle of ventilation network calculation. Combining with theconditions of Sihe mine, a comprehensivesurvey and test to the underground drainage system have been taken. It generates a diagram of pipelinesystem by mine ventilation simulation system (MVSS), calculates the maximum resistance of pipelinesystem in simulation module of gas drainage system, and finally proposes several schemes of optimizationand reformation and solves several problems, such as local resistance is too large in drainage system. The researchshows that drainage resistance is well-distributed after optimization and reformation, and the amountof gas drainage is increased, thus mine safety is greatly improved. Emulation technology introduces a newmean for information management in mine, and helps to control gas more effectively as well.
