针对兖州矿区北宿煤矿矿井资源储量目前只有7645.8万t,其中“三下”压煤4428.6万t,占总储量的57.9%,全矿可采储量不足1400万t,经济可采储量仅为406万t的情况.为解放“三下”压煤,缓解日趋紧张的采场接续、土地塌陷难题,延长矿井开采年限,研究了满足北宿煤矿薄煤层条件下综合机械化充填开采成套开采工艺与设备.
針對兗州礦區北宿煤礦礦井資源儲量目前隻有7645.8萬t,其中“三下”壓煤4428.6萬t,佔總儲量的57.9%,全礦可採儲量不足1400萬t,經濟可採儲量僅為406萬t的情況.為解放“三下”壓煤,緩解日趨緊張的採場接續、土地塌陷難題,延長礦井開採年限,研究瞭滿足北宿煤礦薄煤層條件下綜閤機械化充填開採成套開採工藝與設備.

In Beisu Coal Mine of Yanzhou mining area of mine reserves are now only 76458000 tons, of which“three”coal 44286000 tons, accounting for 57.9%of total reserves, mine recoverable reserves of less than 14000000 tons, recoverable reserves of only 4060000 tons. For the“three”coal, ease the growing tension in the stope, land subsidence problem, to extend the mining life, study the mechanical conditions of thin coal seam under backfill mining complete sets of Beisu Coal Mine mining technology and equipment to meet.
