In order to promote the high-quality development of gas control level, based on the reasearch progress at home and abroad, coal seam gas content measurement, gas emission prediction，gas storge and transportation area identification and delineation，drainage method determination and drainage parameter design，drainage engineering construction, measurement, monitoring, evaluation and adjustment，the whole process of pressure relief gas drainage were established. The connotation of “accurate drainage” of pressure relief gas has explained in terms of “precision”, “accuracy” and “meticulousness”.Taking the key issues of pressure relief gas extraction in deep mining as the core, the main contents as the cornerstone, the key technologies as the support, the means and methods as the approach, and the engineering practice as the verification, a multi-level accurate drainage system framework was constructed. By summarizing the existing common methods of gas emission prediction, a general box model for gas emission prediction was obtained;based on three aspects of theoretical derivation, experimental simulation and field inversion, a high-efficiency pressure relief gas extraction method was proposed. Accurate construction design process of pressure relief gas accurate drainage project based on different design basis was established based on dynamic perception of extraction data, evaluation of extraction effect, optimization of pipeline network, and drainage system decision-making and adjustment. The research content put forward three research topics and research ideas for the accurate control of pressure relief gas drainage and discussed the structure and composition of the cloud platform for pressure relief gas accurate drainage, and applied the pressure relief gas accurate drainage system to the typical high gas in Shanxi Province. This research improved the overall framework of pressure relief gas treatment in deep mines, and provided reference for follow-up research and field application.
