龙固煤矿井底车场辅助排水系统设计

 基于龙固煤矿井下涌水量大，正常涌水量为1220m3/h，最大涌水量为1560 m3/h，一套排水系统布置困难，同时单系统布置可靠性低，设计提出了在井底车场主排水系统的基础上，增设辅助排水系统，形成双排水系统，两套排水系统既相互独立，又紧密联系，经过几年的使用效果检验，表明可靠性较高，效果良好。

Design on Auxiliary Water Drainage System of Mine Shaft Bottom in Longgu Mine

Due to a high mine water inflow in Longgu Mine,the normal mine water inflow value was 1220m3/h and the max mine water inflow value was 1560m3/h.Thus the previous designed single water drainage system could not meet the water drainage requirements.Also the reliability of the single system layout was low.Base on the main water drainage system in the mine shaft bottom,an auxiliary water drainage system was added and thus two water drainage systems were formed.The two set water drainage systems could be mutual independent and closely related.The several year application results showed that the reliability of the two water drainage systems were high and the application effect was excellent.
