Main steps to develop roadway location selection

1) Mainly develop the position selection of the vertical ore body direction of the roadway: delineate the final mining rock belt moving belt, and initially determine the allowable position of the main development roadway outside the surface rock moving belt.
2) Mainly develop the choice of the direction of the roadway along the ore body: According to the principle that the sum of the ground transportation cost and the underground transportation cost is the smallest, the most favorable position of the main development roadway along the direction of the ore body is basically determined.
3) Combine the surface topography and the layout of industrial sites to determine the specific location of the main roadway.
4) Inspect the borehole to further identify the engineering geological conditions of the main roadway (mainly for the shaft).

Chrome Yellow

chrome yellow has high bright yellow pigment, and high hiding powder, well tinting strength, heat-resistance,etc advantages, non-toxic, etc.

Usage:

1. Used in kinds of paints, including water-soluble paint for outside and inside wall, and oil paint including kinds of first coat and face coat such as epoxy, alkyd, amine etc.

2. Used in coloration for construction materials, i.e. mosaic brick, levigation level ground, concrete production, brick for pavement, colorful tiles and man-made marble, etc.

3. Used in coloration for colorful paper.

4. Used in surface coloration for rubber production, and strengthen the abrasion resistance of rubber filling.

5. Used in coloration for plastics, which is harder to fade.

6. Used in detecting the damage degree of machine by its magnetism.
