复杂地质构造工作面开采技术实践

Mining Technology Practice Under Complex Geologic Structure Working Face

摘要: 通过施工改造巷优化工作面布置,对部分工作面进行搬家,小面回采过落差18 m的F₁₃₁断层;在选取合理的爆破参数的基础上,采用放松动炮破顶直接过落差为7.7 m的DF₂₀断层。2种过断层方案在同一工作面的成功应用,降低了复杂地质条件对工作面回采的影响,减少搬家次数,实现连续开采,提高了工作面回采率。

Abstract: Through reforming roadway,the study aims to optimize the working face layout.by moving parts of face’s equipments,the mining face passes through fault F₁₃₁ with a drop height of 18 m.Based on the treasonable blasting parameters,the study carries out the concussion blasting to break top to pass through DF₂₀ fault with a drop height 7.7 m.These two methods are applied successfully in the same work-face to lighten the effects from the complicated geological conditions towards mining,reduce frequency of fully mechanized mining coal work-face removing,achieve continuous mining and improve the recovery coefficient.
