The influence of clip bottles on top-coal´s falling and release properties

Because of the significant influence of clip bottles on top-coal´s falling and release properties, in order to improve the recovery rate, the authors analyze the influencing mechanism and process from the aspects like the clip bottles lithology, the development degree of joints and fissures, the clip bottles layer position, the clip bottles layer thickness, ect. And put forward measures to handle clip bottles layer accordingly to increase the top-coal´s property of falling and release. Through the study of these influence factors conducive to actual production of improving top coal caving resources recovery, we can make mine production achieve better economic benefits.
