从采充均衡论煤矿部分充填开采模式的选择
Because of relative high cost of traditional filling,a new concept of the partial-filling and three technical ways are put forward,including the technologies of partial paste filling in goaf,isolated section-grouting for the overburden bed.
针对传统充填开采成本相对偏高的问题,提出了部分充填开采的概念和3项部分充填开采技术,即采空区膏体条带充填技术、覆岩离层分区隔离注浆充填技术、条带开采冒落区注浆充填技术,分别对其技术原理进行了介绍。
Based on the transverse oscillations and timing structure of bunch pulse that are characteristics in storage ring, it excites the beam to produce the coherent oscillations and then,the electrons of some bunches are destroyed,resulting in a partial filling and uniform filling in storage ring.
介绍了用于电子储存环部分填充和非均匀填充的一种实验装置储存环高频剔除系统 ,它利用储存环中电子运动所具有的横向自由振荡和束团脉冲的时间结构这一特性 ,采用外加激励的方法使其产生共振 ,从而使得储存环中部分束团中的电子丢失 ,形成储存环的部分填充和非均匀填充。
