The trial results show that with the disposal of induced caving roof by presplitting blasting and induced caving roof blasting, about 17.8 m in thickness of rock cushion is successfully formed in the inferior abandoned stope, which can bring down the harm of dashing blast of an explosion caused by roof collapse; apparent run-through flaws arise between presplitting blasting holes, and controllable caving is formed in the roof, abrupt collapse of large area roof is prevented, the productional safe surroundings of underground mining is improved; eventually, the resources' reclamation rate is improved from about 70% to 84.6%, and the dilution rate is abated from 25%40% to below 15%, so efficiently withdrawing is actualized.

试验结果表明：采用预裂爆破与诱导崩顶爆破的方法，通过对顶板的诱导崩落处理，成功地在下方采空区形成了厚度为17.8 m左右的岩石缓冲垫层，有效地降低顶板冒落带来的冲击气浪危害；在预裂孔间产生明显的贯通裂隙，从而在顶板上形成诱导可控崩落，防止顶板大面积的突然垮落，改善地下开采安全生产环境；最终资源的回收率由70%左右提高到84.6%，贫化率由25%~40%降低到15%以下，实现了资源的高效回收。

This paper presented the relationships between roof shapes and form coefficient under wind loads, drainage and corresponding loads caused by rain.

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。

But in realistic reason, the absurdity of the personnel system becomes the parent and teachers toward what student bring pressure emollient to borrow;, The family becomes the student to increase the negative important place, it is student the lessons burden aggravate of motive source and direct source, and became student's mental state to increase negative important source;High test conductor's baton BE also result in this phenomenon of important reason, an acceptance score line stopped the teacher's throat, also taking out to beat the student;The slippery 坡 of the occupation morals of teacher make it the mental acceptance ability of the regardless of student and the healthy body of the student, pass to increase student's lessons to make up the shortage on oneself's teaching, this makes some teachers unilateral to emphasize the result but threw to lose the teacher's original intention then;Lack the emollient direct mechanism, foster the teacher and don't go to the character of raise the oneself, don't go to the science skill of raise the teaching, but measures this to breach the method of science in brief to raise the deceitful examination score of student with the enlargement homework, is not science ground passes to raise student's character, raise the teaching result, but use and should try the educational way leading the student copes with the examination with the speculation prosperity method.

而在现实原因中，人事制度的不合理成为家长和教师向学生施加压力的有力借口；，家庭成为了学生增负的重要场所，更是学生课业负担加重的动力来源和直接来源，并且成为了学生心理增负的重要来源；高考指挥棒更是造成这一现象的重要原因，一条录取分数线勒住了教师的喉咙，也抽打着学生；教师职业道德的滑坡使其不顾学生的心理承受能力和学生的身体健康，通过增加学生课业来弥补自己教学上的不足，这便使有些教师片面强调成绩而丢失了教师的初衷；缺乏有力的监督机制，助长了教师不去提高自己的素质，不去提高教学的科学本领，而是用加大作业量这一简单的违反科学的方法来提高学生虚假的考试分数，不是科学地通过提高学生素质，提高教学效果，而是用应试教育的方式指导学生用投机繁荣方法应付考试。

Reform the goal with development to orient according to the social security system,social security fund is it should is it give consideration to social goal,economic goal,political goal to insist on to raise for,give consideration to the long—term goal and short—term goal, realiz.e combining fairly with efficiency;The social security fund must divide the responsibility border among government,unit,individual to raise rationally,define that govemment and function of the market divide the work;Social security fund is it must pay attention to macroscopical system way choose,is it pay attention to micro technical design and application of field to want too atthe same time to raise for;Social security fund is it should take different raising the way for,raising the way for to different social security project to raise for;Social security fund is it should distinguish regular financial need raising waying,principling of raising the way for etc.different from provisional financial need to raise for.
