No.4 mine (Yili)was briefly introduced. Aimed at the special geological condi-tions of the northern coalfield in Yining mining area,such as ultra thick III-level collapsible epipedon,shallow overburden,no key bearing stratum and “three soft”,the selection of hydrau-lic support was comprehensively analyzed,according to measured data of stratum,laboratory simulation,as well as the investigation of mining under similar geological conditions. Finally, the type of hydraulic support was determined,providing a reliable guarantee for the safe and effi-cient production and large-scale development of coal resource in the whole mining area.
