在基巖電阻率較高的硬地層中,在去除了泥質、孔隙、高礦化度地層水和其他礦物等影響因素后,地層電阻率與緻密圍巖電阻率的差異就被認為是裂縫因素引起的。The hardness and thickness of coal seam play a great role in the vertical distribution of stress in coal and the occurrence of rock bunt under the condition of hard roof and hard floor
在「兩硬」條件下,煤層厚度與硬度的變化對煤體中的應力分佈有著很大的影響,從而對煤巖體系統中沖擊礦壓的發生有著很大的影響。The stress distribution is far from uniform in this stratified rock, the horizontal stress magnitude in hard rock layers is significantly higher the that in soft layers
在軟硬相間的層狀巖體中地應力分佈很不均勻,應力大小與巖層硬度具有正相關性,硬巖中的水平應力大於軟巖的水平應力。Ball hob drill head is applicable for harden rock layer, fine grain granite, and it has below 9 - grade drillability. the compressive strength is no more than 15 of pull coefficient
