平衡压力法在极松散煤巷截流堵水中的应用

 摘要 本文针对黄沙矿112124溜子道巷道截流堵水工程中，因水闸墙无法达到设计压力且112124溜子道煤壁又极其松散，承受水压较低等不利条件,无法成功截流的情况下，提出了平衡压力法截流方案，即：关闭水闸墙上泄水阀门，合理进行升压，通过协调平衡压力法减少截流段承受水压，实现水闸墙在承受较低水压情况下煤巷截流成功，为国内外同类条件下的堵水提供了参考经验。

Balanced Pressure Method Applied to Grouting and Water Sealing of Loose Seam Gateway

According to the floodgate wall not reach the designed pressure and the unsuccessfully water flow closure caused by the loose and other factors of the sidewall in No.112124 chute in Huangsha Mine,a balanced pressure method water flow closure plan was provided.The water releasing valve on the floodgate wall shall be opened and let the pressure rationally increased.With the coordinated balanced pressure method,the pressurized water at the water flow closure section could be reduced.The water flow closure of the seam gateway could be successfully made when the floodgate wall had low pressurized water and could provide a reference experiences to the water sealing under the similar condition.
