Mine look-ahead water exploring orifice outburst prevention and blowout prevention joint water control device

Abstract

The invention discloses a mine look-ahead water exploring orifice outburst prevention and blowout prevention joint water control device. The device comprises a sleeve body, and the sleeve body is fixedly sleeved with an orifice pipe. In the device provided by the invention, a motor and an air cylinder pulled by a stretcher are arranged in the sleeve body, a hollow rotary table is arranged on the air cylinder through a bracket, thus, a drilling tool located on the rotary table stretches out and draws back freely under a supporting action of an output end of the air cylinder, and consequently, the drilling tool can go in and out conveniently in a main hole; the sleeve body is sleeved with the orifice pipe, and a ring-shaped structure bearing frame is arranged through the orifice pipe, thus,a trepanning device and an applier can be conveniently arranged on the orifice pipe in one-to-one correspondence, and so, an intense pressure hole is arranged around a main hole so as to provide a firm protective structure for the main hole; the orifice pipe is orderly connected with a flow distributing pipe, a feeding pipe, a pressurizing pipe, an outburst prevention antifogging device and drilling tool slips, further, a first-stage controllable ball valve, a controllable brake valve, a second-stage controllable ball valve and a pressurizing valve are used, thus, adjusting one by one can be executed according to water fog situation in the main hole, and execution of an accurate water control operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a joint water control device for anti-burst and anti-blowout at an advanced water detection orifice in a mine. Background technique [0002] my country is a vast country with a land area of ​​9.6 million square kilometers, and it is also a large country with mountains, of which the mountains account for about 1 / 3 of the country's land area, and the mountain area accounts for 2 / 3 of the country's land area. The vast mountainous area also makes Our country inevitably has rich mineral resources. At the same time, the vast mountainous area also makes our country have more frequent and higher-level mine disasters. It is well known that in geological disasters in mines, the slight vibration of the earth's crust will also cause large-scale movement of groundwater resources, which shows that groundwater plays a very important destructive role in the occurrence of mine disasters. At the sa...
