Description
The invention discloses and a kind ofly do the method for salt lake mining dynamic change long term monitoring, belong to the mining engineering technical field with the meteorological satellite remote sensing material.
The salt lake mining dynamic change is meant the human general name that salt lake one is comprised a series of variations in aspect such as caused water resource environment such as bittern lake, salt flat and intercrystalline bittern and the hydrology, geology, landforms of adopting under the halogen engineering specifications.Because power and the size of salt lake mineral resources supply agent and the otherness and the perturbation of regional nature Environment Change of human mining engineering influence, the dynamic change in salt lake is very complicated matter of science and technology.It has influence on safe, effective, the permanent operation that salt lake mining is adopted the halogen engineering, also have influence on the big problem of mining area, salt lake resource recyclability balance and environmental change trend and the sustainable development of regional social economy, and in the contrast of whole world change, also occupy certain position.So people take much count of the monitoring of salt lake dynamic change.
In the salt lake bittern development of resources, once adopted automatic observer to monitor local bittern dynamic change situation abroad, produced as Israel's Dead Sea sylvite; The artificial section sampling observation salt lake change of water quality state of adopting is also arranged, produce as U.S.'s Yin Feng salt pond lithium salts; These all are with manual work or semi-automatic utility appliance bittern to be shown in the lake of bittern production to carry out device survey monitoring in limited zonule, and the scope that relates to and the degree of depth are all deposited limit very much, and are that the bittern water body that exposes the face of land is carried out limited monitoring.At home, it is not general that the region of effective monitoring of carrying out in the halogen production is adopted in the salt lake; Only in the Chinese maximum sylvite production and construction of country's tissue, implemented manually to reach the limited monitoring of semiautomatic equipment, Cha Er sweat salt lake, the Caidamu Basin is adopted the dynamic change of halogen process as country connective tissue's key research project one " the Seventh Five-Year Plan ", the 8th Five-Year Plan for national economic and social development in Chinese sylvite development ﹠ construction, reached 10 years the monitoring of (1986-1995), drop into a large amount of manpower and materials, the funds that always drop into are up to more than 8,000,000 Renminbi; Other has the manufacturer's annual 10-20 of input ten thousand Renminbi to carry out the monitoring that repeats that the halogen dynamic change is adopted in the salt lake.Adopt the monitoring method that has generally adopted conventional ground wellbore construction engineering in the halogen dynamic monitoring engineering in the salt lake, the observation cycle of wasting time and energy is also bigger, and its cycle reaches 1～3 month as a result often to obtain an observation and analysis; And the observation area coverage is very limited, generally only is several square kilometres to tens square kilometres.Also there is the ground of small part semi-automatic～supplementary observation of self-reacting device, often interrupts to obtain the Continuous Observation result in big zone because of factors such as bittern salt crust cause observed reading.Moreover also to be subjected to the restriction of conditions such as climatic environment, often can not realize for the monitoring under large tracts of land region and the inclement weather conditions.
Belong to initiative in the similar mining monitoring technology of this invention at home and abroad, and can greatly improve working environment, improve working efficiency, on the continuity in time and space all be the same domain prior art can not compare, have potential very huge economic benefit and social benefit.PRELIMINARY RESULTS of the present invention is proved effective by production practices, as being applied to monitoring result that the present invention obtains in country " eight or the five " key research project (85-802-01) and other prior art means--comprising that artificial surface drilling is long sees, semi-automatic device is surveyed and tagging, the testing result of number reason simulation etc. is corresponding to, some analysis result of the present invention and technical advantage and be that other prior art is irreplaceable, such as having solved the migration of adopting the halogen center and the problems such as differentiation of intercrystalline bittern, deepened the degree of depth and the range of prior art means monitoring.
