同时，还进行了炮孔孔内温度梯度的测量，它与炮孔深度及其温度有关。
The temperature gradient in blast hole was also measured and the temperature gradient was relative to the blast hole depth and its temperature.
同时，还进行了炮孔孔内温度梯度的测量，它与炮孔深度及其温度有关。
In addition, our experiments also indicate that the best depth of blast hole is close to shaft radius.
此外，试验还表明最佳的炮孔深度接近于井筒的半径。
V-shaped notch blasting is that cutting slots with certain depth along axis -direction of the hole is determined according to the blast-crazing, and then load uncoupled charge and detonation.
形刻槽爆破是指在炮孔孔壁上按爆破开裂方向，切出一定深度的轴向对称V形槽，采用不耦合装药结构进行的一种断裂控制爆破。
The results indicate that the decay coefficient of the peak value of blast wave with the distance will be reduced as the hole depth (charge length) is increased.
计算表明，炮孔深度(装药长度)增大，爆炸应力波峰值随距离的衰减指数减小。
The quantity of explosives and the blast-hole spacing are dependent upon the type and structure of the rock and the diameter and depth of the blast holes.
用药量和炮眼间距取决于岩石的范例和布局以及炮眼的直径和深度。
