The design method is described, and the calculation results are presented under the standard air conditioning condition. The working process of the two-stage expander is discussed, and the difference between the two-stage expander and the conventional one is stated. In addition, the influence of the dip angle on the expansion chamber volume is analyzed. The results show that the dip angle has little effect on the expansion chamber volume and it is suggested that the effect may be neglected in the expander design.

Because the increasing of dip angle can lead to special strata behavior which cause difficulties to mining, The strata behavior theory can not be simpely borrowed from that of flat and gently inclined seams. In order to cut down roof accidents and increase production efficiency, the strata movement and stress distribution must be reassessed for seam with deep dip angle.

With a dip angle between 15° and 30°, the uplift of an obducted plate during continental collision is much higher, and able to form a high mountain. The uplift is greatest with a dip angle of 15°; whereas with a dip angle between 30° and 45°, the subduction depth of a plate is much deeper, and able to form a deep basin. The subduction depth is greatest with a dip angle of 45°. When the dip angle is equal to or greater than 75°, subduction and obduction movements between two continents become undistinguishable.
