With the expansion of coal mining westward in China, water inrush from seam roofs has become a prominent safety problem during mining. The roof rock Shilawusu mine characteristics double-layer structure, and overlying separation space formed process poses risk inrush. To ensure production, considering geological hydrogeological data area, core recovery rate, lithologic assemblage index, key aqu...
The study block opens up with the already found oil reservation, through comprehensive analysis to seismic, well logging, log and core data, collate stipulate system of fault, then make sure source fault; Meanwhile we use Geo-Office Jason multiply technology, launch micro faces single sand body spread research. result shows that, mostly have 4 kinds reservation: fault-lithologic, fault block, f...
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
With the advancement of use geophysical methods in mining exploration, possibility restudying known mineral deposits that could have greater potential than previously estimated is opening up, as case Maricunga Belt (MB), which a metallogenic belt located east Copiapó, Chile, with length 200 km and oriented NNE-SSW direction. This hosts significant gold classified porphyry (-copper), epithermal ...
In order to solve the problems of unclear division delta front pre facies belt first member Qing Dynasty in Hei-258 area Daqingzijing south Songliao Basin and lack a unified fine isochronous stratigraphic framework whole region, types genesis cycle interface are summarized by using core data coring well logging more than 70 wells, combined with theory high-resolution sequence stratigraphy sedim...
