| Abstract: | Imitate the software establishment mineral area to concretely work with the FLAC number the noodles mine model, the dynamic state which imitates to study to mine a key layer top rock strata to carry a lotus along with the coal seam delivers process, putting forward a time a key layer to the key layer is carried a lotus and break to break a control function, and give an applied combination carry the calculation method of lotus to compute or predict along with work the noodles open to dig the method of the variety process of size and its dynamic state of carrying the lotus that key layer is subjected to. |
