The contradiction on seizing land between coal production and grain production becomes increasingly apparent.
The problems such as land subsidence, farmland shrinking, reduction in grain yield and others caused by coal mining has been threatening the ecological environmental safety in coal mining area, and imposing serious impact on layout and progress of urbanization for a long time [1].
The north of Ji’ning city, located in alluvial plain of the Yellow River, is a major grain producing area in Shandong, while it is also an enrichment region of coal resources.
For quite a long time, the contradiction of land seizing by grain and coal has been restricting the local social and economic sustainable development because the coal mining subsidence area cannot be in second plough any more.
The two numbers will respectively add to 33015.91 hm2 and 799.52 hm2 in 2020 [4].

The SAGP (Fig. 1) is composed of abrasive grains, pore and bond material.

The equipment used to test the roughness Rv is Mahr Perthometer S2 (vertical resolution:0.8nm, sampling numbers:11,200).The scanning length is 5.6mm.The SEM photos of workpiece surface were tested by scanning electron microscope Hitachi S-4700(resolution: 1.5nm/15KV，2.1nm/1KV) and the amplification is 500.
The percentage of grains in the SSB-2 is about 50% which means that it has a lot of active abrasives.
The percentage of abrasives in the SSB-1 is about 30% and the number of abrasives is less than SSB-2, so each abrasive undertakes more load and the cut depth is deeper under the same conditions.

The chance of positrons thermalised inside grains to reach GBs by diffusion is strongly limited in the ceramics and thus a role of positron trapping in defects inherent to the grain interior is enhanced.
The contribution (ii) depends on the volume fraction of grain boundaries, i.e. on the grain size, while the contribution (iii) depends on the concentration of pores in the sample.
In the Z3Y1C nanopowder, Ps is not formed and the bulk SZ3Y1C-parameter depends on the grain size only.

These patterns are mainly oriented to different tasks, which are too coarse-grained to be easily implemented.
In point of increasing UI knowledge reuse, every UI is divided into many presentation units (PU), which reduces the grain of UI.

More specifically, particles located at triple-junctions of ferrite grains grow up at the expense of particles located inside the ferrite grains.
It should also be noted that the carbide particles have a strong pinning effect and prevent ferrite grains from growing.
The number of defects is also important, and it is known that coarse pearlite, which forms at higher temperatures, contains intrinsically less defects than fine pearlite.
These particles have a strong pinning effect and prevent ferrite grains from growing during annealing.
The deformation of the cementite lamellae accelerates the kinetics since it produces a large number of defects within the lamellae.

A quartz grain size of 50 to 100 µm was determined by microstructural observations.
L denotes the number of the detector module
Discussion and conclusions CPO measurements require the recording of diffraction spectra for a large number of sample orientations.
Due to the grain-shape related reorientation mechanism, the muscovite (001) basal plane pole figures represent an average of all foliations present in rock.
It is possible that microcrack formation in the quartz grains leads to elastic strain release with increasing load.
