Description
Technical field
The present invention relates to a kind of monitoring device, is the device of early warning mine coal and gas outburst risk specifically.
Background technology
Coal and gas are outstanding to be mash gas dynamic phenomenon very complicated under the coal mine, is one of serious natural calamity in down-hole.Under the interference of artificial mining activity, original balancing of stresses state is destroyed in the coal seam, and the physico-mechanical properties of coal (coal mass strength) is by dying down by force, and strengthen relative with gas pressure of geostatic stress (containing selfweight stress, tectonic stress, bearing stress); Under the effect of geostatic stress, the coal seam prototype structure is destroyed, the production crack, form a large amount of scope of freedoms, cause the adsorption gas that is rich in the coal seam fast, a large amount of desorb, be transformed into free gas, form the huge gas bulbs of pressure, when this energy accumulating arrives to a certain degree, the soft coal that orders about after the fragmentation is broken through burden, and moment is ejected a large amount of gas (reaching millions of cubic meters) and coal (reaching ten thousand tons) from the coal seam, cause the fire damp dynamic phenomenon.The coal mining degree of depth is dark more, and the outstanding energy that discharges of coal and gas is big more.When coal seam heading, raise advance and stone door punching coal, it is outstanding that coal and gas take place easily, and coal and gas also can take place the stope of the mine that has gives prominence to.
Coal and gas are outstanding to be a world-famous puzzle; According to statistics, there are coal and the outstanding generation of gas in 18 countries and regions such as nearly in the world at present China, France, Russia, Poland, Japan.
One of coal and the gas protrusion phenomenon is the most serious, harmfulness is maximum country take place in China in the world, coal takes place account for countries in the world with the outstanding total degree of gas and always give prominence to more than 1/3rd of number of times.Investigation statistics according to 2007, China has 19 provinces, 45 mineral bureaus, 647 pairs of state-owned emphasis mines, 403 pairs of Township Coal Mine, coal and gas take place altogether outstanding 14300 times, dead 1266 people, prominent altogether coal output 815800t, average intensity of outburst is 27.0t/ time, accounts for 35% of the outstanding total degree in the world.Surplus the outstanding number of times that intensity of outburst surpasses 1000t reaches 100 time, as on August 8th, 1975, self-sufficient and strategically located region mineral bureau three converges the coal that China's maximum takes place when the coal seam is exposed in the horizontal galleries of one ore deposit, dam+280m gave prominence to gas, and intensity of outburst reaches 12780t, gas emission 1400000m

Giving prominence to that China is most is coal and CH
4Outstanding, but rock few in number and CH are also arranged
4Outstanding, sandstone and CO
2Give prominence to and coal, sandstone and CO
2Outstanding.Along with the depth of excavation constantly increases, geostatic stress and gas pressure continue to increase, and the geological conditions of coal mining and technical condition are also increasingly sophisticated, and the number of coal and gas outburst mine increases, and number of times is frequent, and intensity strengthens.
Coal and gas outburst prevention treatment are global difficult problems always.Forecasting coal and gas are outstanding, importantly seek or determine the sensitive parameter index and the threshold thereof of prediction outburst danger.The achievement of the outburst prediction prediction research work that many decades is carried out all shows:
1. determine that the critical indicator that can adapt to each projecting mine is very difficult, different mines have different critical indicator values; Be exactly in same mine, same coal seam, in different dark, the different zones of adopting, the outburst danger criterion is also inequality.
2. in recent years, prediction index having occurred does not exceed standard (as drillings amount, K yet
1), but outstanding example has taken place in the mining process of reality.
The problems referred to above, be because:
1. in the different outstanding mining areas that has, outstanding three elements take place in influence: coal petrography environment (coal seam characteristic, geological structure), gas, geostatic stress have nothing in common with each other, and people are difficult to find the identical mining area of condition of coal seam occurrence.
2. both be exactly in same mine, same coal seam, in different zones, in different adopting deeply, outstanding three elements take place and have nothing in common with each other in influence; Variation has taken place in the character, the condition that are analytic target.
3. point prediction and excavation operation have individual blanking time on space-time.Work team at least, a couple of days is just once predicted at most, obviously, early stage, prediction result was difficult to represent the coal petrography characteristic of later stage during excavation operation on space-time.
Summary of the invention
The objective of the invention is to, the equipment of coal and gas outburst risk in a kind of real-time tracking early warning mine is provided, can be in time and the outstanding danger that takes place of reliable prediction work plane coal and gas, cause great casualties when avoiding outstanding accident to take place.
The present invention is based on following design and form: coal and gas are outstanding to be a kind of well dynamic phenomenon that can discharge huge energy, and so big power destruction takes place, and can have precursor information.The long-term work place study of applicant shows: before outstanding the generation, a large amount of anomalies is all arranged, as wall fall slag, the serious compressive deformation of support, produce a large amount of coal reports (the deep coal petrography destroys the sound that produces), gas emission are suddenly big or suddenly small, the thickness in coal seam or structure (tomography, hardness) change etc.Therefore, the outstanding best bet of control coal and gas is exactly can the relevant outstanding data (geostatic stress, gas) of continuous acquisition, the danger of giving prominence to by real-time analysis, prediction generation coal and gas.Obviously, if can research and develop a kind of device that collects these precursor informations and analyze, handle, judge and in time report to the police that can be real-time, just can avoid the generation of great personnel casualty accidents.
