Abstract
The utility model discloses a mining condensing expansion cracking device which is characterized by comprising a sealing ring 1, condensing agent pipelines 2 and a water injecting pipeline 3. The water injecting pipeline 3 passes through a central hole of the sealing ring 1, and the condensing agent pipelines 2 pass through holes around the sealing ring 1. The mining condensing expansion cracking device cracks rock bodies by expansive force of water condensation, and is good in safety, high in controllability, and simple and reasonable in structure.
Description
Affiliated technical field
The utility model relates to fracturing device, especially relates to a kind of mining condensation expansion fracturing device.
Background technology
At present, the dynamic disaster that occurs in order to administer the coal mine underground recovery process generally is to take unloading pressure means to reduce stress, and method commonly used has explosion, fracturing etc.But these procedures are relatively fierce, and are wayward, tend to cause gas, dust explosion or cause the danger such as unforeseen stress transfer, thereby bring new safety problem.
Summary of the invention
The utility model purpose is to overcome the deficiency of above condition, and a kind of mining condensation expansion fracturing device is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
The utility model is comprised of filling pipe, condensing agent pipeline, sealing ring, and filling pipe passes the center hole of sealing ring, and the condensing agent pipeline passes sealing ring hole all around.The utility model condensing agent pipeline is marked with the length scale.The agent of water condensation by contact, after condensation was frozen, volume increased, and can produce very large expansion force in enclosure space rock mass is broken.By the length scale on the condensing agent pipeline, can adjust the position of condensation expansion fracturing.
The beneficial effects of the utility model are, safety is good, and controllability is high, and is simple in structure, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model elevation.
Fig. 2 is the utility model condensing agent pipeline enlarged drawing.
Fig. 3 is the utility model lateral view.
Among the figure: 1-sealing ring 2-condensing agent pipeline 3-filling pipe
The specific embodiment
Below in conjunction with accompanying drawing implementation of the present utility model is further described:
Embodiment 1: a kind of mining condensation expansion fracturing device of the utility model, formed by sealing ring 1, condensing agent pipeline 2, filling pipe 3, as shown in Figure 1, this device is put into the boring of accomplishing fluently, sealing ring 1 and hole wall close contact, inject enough water from filling pipe 3, from condensing agent pipeline 2, inject condensing agent after filling with, adjust the position that condensing agent discharges by the length scale.
