According to the results of experiments, the mechanism was deducted: the pre-gelatinization starch molecular limited the spread of the other starch molecular and decreased the amount of hydrogenous bond, which lowed the strength of rice noodle. However, the curly starch molecular was propitious to improve the maximum strain.

根据实验结果，推断其机理为：预糊化的淀粉分子限制了其它淀粉分子在糊化过程中的伸展，减小了老化时淀粉形成氢键的数量，从而降低了切粉的强度；卷曲的淀粉分子有助于提高切粉的最大应变。

The top coal fracture is described distinctly under the condition of different roof span and mining technology parameters. Through orthogonal experiment of numerical simulation, the rational pretreatment span of hard roof is determined, and the rational working resistance of support is selected also. As a result: the hard roof is effectively controlled not only to protect the working face but also to promote the caving of hard top coal to increase the recovery ratio.
