Description
Technical field
The utility model belongs to earth gas and looks for the ore deposit technical field, particularly relates to a kind of latent metallic ore earth gas and gathers drilling tool, looks for the sampling apparatus in ore deposit by the latent metallic ore field of reconnoitring of the constituent content, the particularly area of coverage of measuring material-earth gas.
Background technology
Latent metallic ore earth gas (metal gas in the earth) method is a kind of new geochemical exploration method that development in recent years is got up, and its development is relevant with the requirement of global mineral exploration situation.Because along with the minimizing day by day in surface occurence ore deposit, look for the emphasis in ore deposit to look for latent, half buried ore by looking for the near surface ore deposit progressively to turn to, comprise the ore deposit of burying under the covering of middle-shallow layer drift load, look for difficulty and the risk and day sharp increase in ore deposit.Simultaneously, the huge and many areas of area of coverage area have good one-tenth ore deposit distant view.Therefore, the novel geochemical exploration technique method of research area of coverage searching buried ore has very important realistic meaning.
On the research tendency and present situation of present area of coverage geochemical exploration technique method, earth gas method is one of method of tool application prospect.
Last century early eighties, Sweden Pohle moral company research has also proposed a kind of new " metal gas " measuring technique (passive ground vapour method), by at more than 30 mineral deposit experimental studies, method of proof is effective.States such as Czech, Russia, Germany, Australia, Canada successively carried out the research of this respect subsequently.; because the theoretical foundation understanding difference to method is bigger; add up-sampling and analysis means is limit; in the nineties in considerable time in last century; the external research of having abandoned this respect substantially; and China adheres to this respect research always, and has been applied to the actual miner of looking for of the area of coverage and makes the very significant real achievement of obtaining.
Latent metallic ore earth gas can be divided into by the difference of open-air enriched gas method: active method earth gas is measured and passive means earth gas is measured two kinds.
1 passive means:
Trapping agent buried be formed on the underground method of sampling of carrying out enrichment and be called passive means by operation of nature.Trap was embedded in the soil 15～60 days, makes the progressively accumulation under normal pressure of metal earth gas, fetch trap then, analyze the constituent content of the trace materials of catching.Advantage is to be subjected to climatic effect less, requires lower to depth of cover and character.Shortcoming mainly is that the sampling time is long, and the rate of recovery is low, can't adopt the liquid trap agent.At present, passive means seldom adopts.
2, active method:
The method that adopts negative high voltage preenrichment method to carry out the field condition sampling is called active method.But because of its quick, convenient multiple spot collection combination sample, practical application is the most extensive.
Its sampling apparatus mainly is made up of screw thread sampler, silicone tube, strainer, trap and pressure reducer.Active method earth gas measuring technique is the deep penetration geochemical exploration technology of China's original creation, by research for many years, exist the unusual phenomenon of " gaseous state " metallic element progressively to obtain confirming in the near surface soil air of ore body top, show that ground vapour measuring method area of coverage buried ore has good prospect in reconnoitring.But, because earth gas is different from conventional gas, the conventional gas sampling apparatus collection earth gas that past adopts has run into very big problem, disturb, lack degree of depth control and real-time conditions observation etc. as big aerosol, therefore, the special-purpose sampling apparatus of research earth gas becomes a key technology that breaks through technical bottleneck.This patent emphasis solves an above difficult problem:

At first, gas flow and sampling quantity can't reach requirement.Because this sampler probe is too small with the soil contact point area, adds that the extruding of drilling tool precession process causes the minimizing in soil aperture, therefore, can't satisfy earth gas sample desired big flow (＞5L/min) and the single hole volume of bleeding reach the sampling condition of 5L.
Secondly, lack real-time conditions observation module.It is significant to the research of earth gas to measure conditional parameters such as the soil moisture, humidity, and these parameters not only help to understand earth gas abnormal formation mechanism, but also can determine the optimum sampling condition, improves earth gas certainty of measurement.
