Optimization and Reformation of Gas Drainage System Based on Emulation Technology
With the growth of the service life of mine and increasing of extending mining, underground operation requires more and more new drilling field of gas drainage. The increase of the length of drainage pipe causes rising of the resistance of gas flow and changes the reasonable resistance distribution of the initial drainage system, and it also affects the efficiency and reliability of gas drainage. In order to improve efficiency and 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 pipeline with the principle of ventilation network calculation. Combining with theconditions of Sihe mine, a comprehensive survey and test to the underground drainage system have been taken. It generates a diagram of pipeline system by mine ventilation simulation system (MVSS), calculates the maximum resistance of pipeline system in simulation module of gas drainage system, and finally proposes several schemes of optimization and reformation and solves several problems, such as local resistance is too large in drainage system. The research shows that drainage resistance is well-distributed after optimization and reformation, and the amount of gas drainage is increased, thus mine safety is greatly improved. Emulation technology introduces a new mean for information management in mine, and helps to control gas more effectively as well.
