FINDING WAYS TO IMPROVE PRODUCTIVITY DRILLING WELLS IN STRONG ROCKS<\/strong><\/h3>\n

Summary.<\/strong> The purpose of the work is to invent a method and develop a tool for effective drilling of strong and especially strong rocks with the least expenditure of both energy and money for the drilling tool. Currently, in rocks, the most time-consuming and expensive is drilling wells in strong and especially strong rocks. Despite numerous attempts to solve the problem of drilling strong rocks, an effective solution to this problem has not yet been found. The problem is that the introduction of drilling tools into these rocks requires considerable effort and work to destroy these rocks. This requires high strength and durability of the drilling tool, which is limited by the properties of known materials used. The solution to this problem may be to strengthen strong and drill wells in particularly strong rocks by transferring them to a stressed state or creating a grid of cracks in them, which will significantly reduce the effort and work to introduce the tool into the rock, as well as its abrasive wearout. This article proposes a new method and device for creating cracks on the mine face surface in durable rocks for their further drilling by cutting. A brief description of the new method of impact-cutting drilling of strong rocks is given. Sketch drawings of a previously unknown device for impact-cutting drilling of strong rocks are provided and a description of its work is given. The advantages of this method and the device are indicated \u2013 in solving the problem of drilling strong rocks.<\/p>\n

Key words: <\/strong>shock-cutting bit, teeth, drilling wells, rocks, mesh cracks.<\/p>\n
