Description
Technical Field
The invention relates to the technical field of carbon dioxide fracturing, in particular to a carbon dioxide fracturing device, a heating material and a using method thereof.
Background
With the development of urban underground railways in China and the continuous maturity of urban subway networks, subway stations and lines usually contain pile structures and need manual hole digging pile construction. When the manual hole digging pile is contacted with a rock stratum with higher hardness, a manual matching mechanical digging method or an explosive blasting method is adopted, the manual matching mechanical digging method is difficult to construct, the working efficiency is low, a large safety risk exists when people construct the pile below, and the explosive blasting method pollutes the environment, is complicated in working procedure, is unsafe and has high cost.
High-pressure gas blasting is explosive-free blasting, and in the early 60 s of the twentieth century, developed countries such as the United states and the like begin to research a physical blasting method, high-pressure gas is generated by mechanical equipment such as a compressor or through physical change (for example, liquid state is changed into gaseous state), a high-pressure gas blasting pipe is installed in coal and rock, and high-pressure gas in the blasting pipe is released instantaneously through a manual and electric operating mechanism so as to expand and work on surrounding media to break the high-pressure gas. The explosion principle is that liquid carbon dioxide is filled into an explosion tube, then the explosion tube is arranged in a drill hole, a power supply is switched on, and an electrode heating element heats the liquid carbon dioxide to become gaseous carbon dioxide, so that the gas pressure in the explosion tube is increased. When the gas pressure is greater than the shearing stress of the cutting disc at the tail end of the blasting tube, high-pressure gas is released quickly through the valve at the tail end of the blasting tube to provide aerodynamic force and thrust for an exploded object, so that the medium is expanded and collapsed.
At present, the method gradually applies the destruction of the medium by using the liquid carbon dioxide to the fields of blasting sources, metal product forming, underground mines, surface mining and the like, and becomes a novel potential blasting apparatus. The carbon dioxide blasting technology is initially applied to mining, and is used for replacing explosive blasting due to the stable chemical property of carbon dioxide, is used for blasting coal falling in underground coal mines, and can effectively control the generation of blasting sparks, so that the gas and coal dust explosion is avoided; subsequently, the technology is popularized to gas blasting guide release, roadway profile pre-splitting forming and the like of underground high-gas coal mines, and is highly favored by underground mines. In the 21 st century, domestic carbon dioxide explosion equipment manufacturers gradually come up (main parts still depend on import), the application range is further widened, underground mining is expanded to open-pit mining, and the coal mine field is spanned to a non-coal mine, so that a plurality of successful paradigms for applying the non-coal mine appear.
However, the heating material adopted in the current carbon dioxide fracturing blasting method has less heat productivity, so that the liquid carbon dioxide cannot be rapidly expanded and blasted, the blasting time is longer, and a large amount of dust and noise are generated during the rock wall breaking due to low blasting energy and relatively low blasting speed, so that the whole blasting process is influenced. Therefore, in view of the above circumstances, there is a need to develop a heat generating material for a carbon dioxide cracker, which can complete blasting in a short time, has a smooth blasting surface, and generates little noise and dust during blasting.
