| 摘 要： | 通过对岩石破裂过程中声发射活动的实验探测，证明自控水力截齿在一定的水力参数和截割条件下，对岩样的潜在损伤范围及实际破碎沟槽宽度都明显大于同样截割条件下的普通截齿，从而为采掘机械应用少截齿配置方案以提高块率提供了一条可行的技术途径。

| Abstract: | The experimental results of the measurement of acoustic emission activity during rockfracturing process show that the potential damage zone and the real breakage width of theself-controlled hydro-pick are obviously larger than that of common pick within some hydralic parameters and cutting conditions,which provides a feasible technology way to enhance debris rate of mining machinery with less pick scheme. |
