Physical Simulation of Failure of Overburden Physical simulation with similarity materials is made in line with the specific mining and geological conditions of the 6206 mining face.
Fig. 3 Result of physical simulation of the failure of overlying strata with similarity materials Through comprehensive analysis of the heights of the fractured zones obtained with various methods as described above, it can be seen that when the full-seam mining method is used with the effective mining thickness of 6-m, under the mining conditions with a cutting-caving ratio of 1:1, the height of the fractured zone actually observed is 115-m with a height/mining thickness ratio of 20.15.

The local non-profit organization operates through a partnership between local businesses, property owners, residents and members of other local associations, and is structured into several committees, combining different activities in four themes that intersect: -Organization, to build consensus and partnerships between stakeholders; -Promoting and marketing, to create a positive image that allows you to rediscover its identity to the community and improve the confidence of consumers and investors in the commercial district, through special events and retail promotions; -Design, to create an attractive environment by directing attention to all its physical elements: public and private buildings, storefronts, signs, public spaces, car parks, street furniture, public art, landscaping, merchandising, window displays, and promotional material.

It has great significance on early prevention of fracture failure of ferromagnetic materials and major malignant accidents[1-2].
Based on the principle of stress-magnetization effect of ferromagnetic components, attribute is assigned to ferromagnetic material with different prefabricated defects by using the finite element simulation software(ANSYS)[6].

The die is manufactured in a single piece and the material flow is correct through pockets and variable bearing lengths.
A similar behavior is found also for the die temperatures: initially temperature rose to a peak then colder material arrived reducing the measured values.
It is worth noting that such reduction of temperatures generated no changes of extrusion load thus without influencing what happen to the material in the die filling and most likely also in welding.

To loss rate: when the feeding speed is small, not enough to change the movement of ginkgo, there is a critical value, before the critical value, with feeding speed increasing, the loss rate decreases, when the feeding speed is greater than the critical value, the wind changed material force, with the increasing of feeding speed, will part of the ginkgo be blown out from the wind outlet door, loss rate increases.

Many experimental studies have revealed that the recovery of very fine particles by flotation can be much lower than for the same material in larger sizes [9, 12].
The received pan was placed at the bottom of the sieves to receive the final undersize material.
