Example Embodiment

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples.

[0018] The invention provides a method for using a deep well roadway anti-impact synergistic pressure-yielding annular support. like Figure 1 to Figure 4 As shown, including bracket construction, pressure control, displacement monitoring three parts:

[0019] Step 1, connect the support and pressure column 6 with the connecting bearing tube 7 in turn, and let the pressure spring 2 be nested, and the support and pressure plate 3 and the support and pressure column 6 are welded and fixed, and then use this part to pass the external bearing tube. 7. The upper thread is connected with the external bearing port 5 on the periphery of the ring support 1 to form an anti-shock synergistic pressure ring support;

[0020] In step 2, the support is placed in the deep well roadway, the hydraulic pump is used to connect the hydraulic control port 4, the hyd...

Abstract

The invention relates to a roadway rock burst prevention and control technology, and discloses a using method of an anti-impact collaborative yielding annular support for a deep well roadway. The using method comprises three parts of support building, pressure control and displacement monitoring. The support building includes the steps that a supporting pressure-bearing column is sequentially nested with a connecting bearing pipe and a yielding spring; a supporting pressure-bearing plate is welded and fixed to the supporting pressure-bearing column; and then the supporting pressure-bearing plate is connected with an external bearing opening in the periphery of an annular support through threads on an external bearing pipe. The pressure control includes the steps that a hydraulic pump machine is connected with a hydraulic control port; oil is injected into a hydraulic cavity; and the hydraulic control port is blocked after injection pressure is controlled. The displacement monitoring includes the steps of observing a pressure change in a hydraulic cavity by using a pressure gauge, monitoring the displacement change of each supporting pressure-bearing plate, and carrying out anti-impact yielding by using a yielding spring and a hydraulic mode. The deep well roadway can be supported through the using method of the anti-impact collaborative yielding annular support for the deep well roadway, so that on one hand, safety, reliability, convenience, rapidness and low cost are achieved, and on the other hand, anti-impact yielding is effectively conducted.

Description

technical field [0001] The invention relates to a roadway rock burst prevention technology, in particular to a method for using a deep well roadway anti-shock cooperative pressure yield ring support. Background technique [0002] Coal resources are mined from the shallow part. With the coal mining, the burial depth of the mined coal seam will inevitably increase. The expansion of mining scale and the improvement of mechanization level have accelerated the development of production mines to deep parts. Deep mining of coal mines is a problem that most major coal mining countries in the world will face at present and in the future. With the large demand for energy and the acceleration of mine depth, some coal mines have begun to turn or are about to enter deep mining. [0003] With the continuous increase of mining depth, the mine has gradually encountered problems such as strong mine pressure, difficulty in roadway maintenance, rising ground temperature, difficulty in explorat...
