In combined with the blasting parameter design for the sectional blasting with a full length borehole in the coal bunker,the paper certified the rationality of the millisecond time set by the method.

根据爆破自由面形成的时间和破碎岩石飞行的时间，探讨了深孔爆破各作用炮眼的合理延期时间；同时结合全深度一次钻孔分段爆破煤仓的爆破参数设计，验证了利用该法确定微差时间的合理性。

Drills are among the basic tools of industry, building, and manufacturing. Dudley tells time by the television programs he is missing while hiding away from Harry's letters from Hogwarts on the rock and whines that his father wouldn't let him bring the television, his video games, and computer with him in his duffle bag.

钻孔机是工业制造，建筑业，制造业的一项基本工具，当为了躲避哈利从霍格沃茨的信而住在岩石上的时候达利不停的报时说他在错过什么电视节目，并且哭着抱怨他的父亲不让他在他的行李袋里装上他的电视，录象机和电脑。

Furthermore the formulae for calculation of the magnitude as well as the method for calculation of the elastic coefficient of the rock around the bore hole are derived.

文中还导出了计算地震震级的公式和计算钻孔周围岩石弹性系数的方法，不但解决了上述难题，还使计算大为简化。

At the same time, mechanical tunnel boring equipment will grind up the rock and soil detached by the melted kerf and pass it to the rear of the machine for disposal by conveyor, slurry pipeline, etc.

同时，机械的隧道钻孔设备会磨碎的岩石和土壤，被熔化的切口分离并传到机器的后面，由传送机、输浆管道等进行清理。

The present invention relates to a rock drill bit (1) for percussive drilling.

Because concern produces large rock collapse accident, profit leaving the United States ever made river water when 1969 firm chute, right base cliff undertakes consolidate, carried out an extensive bore and sampling plan picture.

因为担心发生大型岩石坍塌事故，1969年时曾将河水引离美利坚瀑布，对基岩进行加固，并实施了一项广泛的钻孔和采样计画。

From the bottom up, the strata are the Fuxian, the Yan'an, the Zhiluo and the Anding Formations. In the past, it was thought that only the Yan'an Formation contains coal in the Jurassic systerm of the basin. However, recent explorations have shown that the Zhiluo Formation also has some minable coal seams in a certain area.

以往认为鄂尔多斯盆地的侏罗系延安组为含煤岩系，其他均为不含煤的地层，在近几年来的勘查中，发现直罗组也存在具有一定分布面积的可采煤层，笔者通过直罗组岩石露头、钻孔岩心和测井曲线的分析研究，划分了直罗组沉积相，并探索了直罗组的聚煤规律，对煤层进行了预测。
