It is important to reduce the span of the hard roof to avoid its impact load on supports. However, at longwall top coal caving face, the periodical weight of roof is a main factor that crushes the top coal, which is beneficial to the top coal recovery. How to use the roof pressure safely is of crucial importance in top coal caving. Based on field monitoring, theoretical analysis of strata movement, the numerical model of compound structure of hard roof stepped cantilever and the top coal cantilever beam is built, and the parameters of the model are also determined. The elasto-plastic finite element method is used to analyze the effect of hard coal fracture under the abutment pressure of hard roof, and the cracking coefficient is defined according to the stress state of the element.

通过对岩层移动的现场观测，建立了&两硬&条件综放采场台阶悬臂—悬臂梁组合的煤岩组合结构力学模型，并以此煤岩结构为基础，建立&两硬&条件综放采场顶煤压裂的有限元数值模型，分析了坚硬顶板不同来压步距对坚硬顶煤的压裂效应，并确定了合理的支架阻力，从而对坚硬顶板进行有效的控制，消除坚硬项板对采场的冲击隐患，同时保证采场矿压对坚硬顶煤的有效压裂，达到提高顶煤回收率之目的，由此形成了坚硬顶煤、坚硬顶板条件下综放采场围岩控制的基本理论和方法。

Paired Samples T test revealed that both the LT and VL decreased (P.01), the AD increased (P.01) after cycloplegia regardless of their refractive state. The AL increased for hyperopic eyes (P.05) and decreased for myopic eyes (P.01) after cycloplegia. For hyperopic eyes, the major keratometer K1 increased (P.05) while for myopic eyes, the major keratometer K1(P.05) and minor keratometer K2 (P.01) decreased after cycloplegia. The mean corneal power of zones 5 mm (MD5) and 7 mm (MD7) decreased with myopic eyes decreased dramatically (P.01). The mean refractive power of the lower half vertical meridian is greater than that of upper half; and the mean refractive power of the lateral half of the horizontal is greater than that of the medial half.

结果：不论远视眼、正视眼还是近视眼在睫状肌麻痹后前房加深（P.01），晶状体变薄（P.01），玻璃体腔径缩短（P.01）；但远视眼睫状肌麻痹后眼轴增长（P.05），近视眼眼轴缩短（P.01）；远视眼睫状肌麻痹后角膜曲率K1增加（P.05），近视眼睫状肌麻痹后除K1降低外（P.05），K2以及以角膜中心点为中心，直径为5mm、7mm的环平均角膜屈光度（MD5、MD7）均降低（P.01）；此外，垂直径线上方的平均角膜屈光度小于下方的平均角膜屈光度而水平径线鼻侧的平均角膜屈光度小于颞侧的平均角膜屈光度（P.01）。

The half-life day of HCH, DDT and chlorpyrifos was 27～32, 27～33 and 22～24 respectively and the residue were detected in the substrates and fruitbodies when fungi were inoculated to the substrated, There were no cypermethrin detected in the fruitbodies, and it's half-life day in the substrate was 19～20. Carbendazim used for control germina was also detected in the substrates and fruitbodies with a half-life from 19 days to 20 days. Because of it's short half-life (2 days to 4 days), the degradation of Chlorothalonil in substrates and fruitbodie were quickly and no chlorothanonil were detected both in the substrates and fruitbodies when harves.

Goals are proportion in the first half and the second half. Goals flood tide appear in the first 15 minutes of first half and second half, and the amount of goal reduce more and more as the time goes by during the other period of time. The main districts of goal are 1 section and 2 section. Besides, the big forbidden zone spread to 30M line section also become the main district of goal.
