    The optimum range of hole size for DTH drilling is 90 mm (3.5”) to 254 mm (10”). Smaller holes are generally drilled using tophammer drill rigs, and larger holes generally use rotary drill rigs. As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. i.e. standard 102 mm (4”) hammer will drill a hole down to a minimum diameter of 102 mm (4”).

    2019-3-18 · Reverse circulation down-the-hole (RC-DTH) air hammer drilling is a fast and cost-effective method for hard rock drilling. As the air RC drill bit is the heart for RC-DTH air hammer drilling system to form the reverse circulation, a large-diameter RC drill bit was innovatively designed and numerically optimized with respect to the suction ability.

    2019-8-28 · The selection of hammer size is largely determined by the hole diameter and type of rock formation. The optimum blasthole range for DTH drilling is 3 ½ to 10 in. Smaller holes are typically drilled with a top hammer rather than DTH hammer, and larger holes generally use rotary drilling technique, mainly with the focus on hole straightness.

    2019-8-28 · A hydraulic transient, also known as water hammer or hydraulic shock, is a sharp pressure surge or a wave produced when water flow is forced to stop suddenly or change direction abruptly. Power failure of pumps, sudden valve actions and the operation of automatic control systems can cause a high pressure wave to propagate in pipeline systems, including domestic water-supply networks.
