Abstract

A coal seam potential energy body physics blast control method uses a drill-push one-piece outburst prevention drilling machine and a coal-gas separator to work; the working method comprises the following steps: determining positions, depth, numbers, drilling angles, two-hole spacing and two-hole ending distance of drill holes; using a hydraulic system to provide horizontal and vertical support for the drilling machine, so the drill-push one-piece outburst prevention drilling machine becomes one piece with the tunnel; carrying out reference drilling on the coal seam so as to lay the base for sleeve devices and pushing work; using the coal-gas separator to replace a guide device, making safety leakage preparation, and carrying out regular drill-push work; adding drill rods and sleeves according to the maximum push distance of the drilling machine until the drill hole reaches the project designed depth. The method can leak and discharge gas or carbon dioxide in the coal seam potential energy body having physics blast risks, thus thoroughly preventing coal and gas protrude accidents, and providing safe production conditions for coal enterprise and miners.

Description

technical field

[0001] The invention relates to safety production technology in the field of underground coal mining, in particular to a method for preventing and controlling the physical explosion of coal seam potential energy bodies. Background technique

[0002] For a long time, coal and gas outburst dynamic disasters during coal mining have always plagued the coal mining process of underground coal mines. my country is the country with the most serious coal and gas outburst disasters in the world. The power disaster prevention technology in coal mining has always been listed as the top priority of safety production technology planning, but due to the inaccessibility of coal and gas outburst disasters. The reader of the "Regulations on the Prevention and Control of Coal and Gas Outbursts" describes coal and gas outbursts in this way: "Coal and gas outbursts are broken coal, rocks and gas under the joint action of in-situ stress and gas, which suddenly emerge from the coal...

Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the specific implementation will be described in detail below in conjunction with the accompanying drawings.

[0033] In order to explain the target of this method more clearly, it is necessary to analyze the ins and outs of the concept of coal seam potential energy body physical explosion, that is, how to define and quantify it. Here we use the "principle of returning to the original method" and the theory of relativity "The principle of space-time replacement method", that is, since there is no such thing as something out of nothing in nature, and there is no law of effect without cause, this allows us to find out the truth of coal and gas outburst, that is, the main law of its existence and the main reason for its occurrence. The contradiction points out the direction, together with the quantifiable data information and unquantifiable perceptual inf...
