Benefits of technology

The patent text describes different mining bits with different designs and arrangements of wings and cutting elements. These bits can be used for mining materials such as coal or rock. The technical effects of the invention include improved performance and efficiency of the mining process, as well as reduced wear and tear on the mining equipment. The method of assembly also allows for easy replacement of parts and components. Overall, the invention provides a more robust and durable mining bit that can withstand the harsh conditions of the mining industry.

Problems solved by technology

Also contributing to decreased ROP may be an inability to remove cuttings from a borehole as needed.
Lack of cutting removal may be due to insufficient cleaning from flow nozzles because of improper nozzle size or placement on the drill bit.

Embodiment Construction

[0041]In one aspect, embodiments disclosed herein relate to equipment used in the mining industry. More particularly, embodiments disclosed herein relate to mining claw bits.

[0042]The present disclosure comprises various embodiments of a rotary mining bit, which may be used for the drilling of blast holes in mineral deposits for the placement of explosive therein. The bit may be adapted for use in relatively soft formations as well as in harder mineral deposits. While the present bit is particularly adapted for the drilling in the mining industry, it may also be adaptable for the drilling of holes for gas, oil, and water wells, as well as for the drilling of other holes for various other purposes.

[0043]FIG. 1A shows a mining bit 100 in accordance with embodiments of the present disclosure. Mining bit 100 includes a bit body 102 having a central axis 103, and further includes a non-conical, polygonal, or faceted forward section 104 and a rearward attachment section 106 for connection...

Abstract

A mining bit includes a bit body having a central axis, the bit body having a forward portion with faceted surfaces and a rearward attachment portion. The mining bit further includes a plurality of wings extending from the faceted surfaces of the bit body and arranged about a central hub. A plurality of cutting elements are disposed on distal ends of the wings.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Application claims the priority of a provisional application under 35 U.S.C. §119(e), namely U.S. Patent Application Ser. No. 60 / 970,146 filed on Sep. 5, 2007, which is incorporated by reference in its entirety herein.BACKGROUND[0002]1. Field of the Disclosure[0003]Embodiments disclosed herein relate generally to equipment used in the mining industry. More particularly, embodiments disclosed herein relate to mining claw bits.[0004]2. Background Art[0005]Relatively large rotary drills may commonly be used in the mining industry for the drilling of holes in ore beds and strata. Large earth boring machines capable of drilling to depths of 500 feet or more may be used in a process which involves mapping out a drill pattern, drilling a blast hole, and filling the blast hole with explosives. Blasts may consist of 200 to 300 holes, each hole containing up to one ton of explosives. Various types of drill bits have been developed and used in ...
