For a long time, the university's sports teaching too much emphasis and attention to students' curricular teaching, and often overlooked exercise education of college students in extra-curricular, simple lesson alone is difficult to achieve the goal of teaching physical education health curriculum. This is not consistent with the guiding ideology of health first, making the physique of college students has declined, extra-curricular physical exercise is an important part of the University of Physical Education. Major factors affecting college students' extracurricular physical exercise can be learned, the factors affect students in extracurricular physical exercise include both subjective and objective, extra-curricular sports activities contribute to achieve the purpose of schooling, but also an important way to enhance physical development of students. This paper mainly discusses the research objects and methods, results and analysis, as well as analysis factors impact college students to participate in extracurricular physical exercise. © Trade Science Inc.

To solve the security problem of fully mechanized mining with sub-level caving in the super-thick coal seam under the reservoir, by the flushing fluid leakage measurement in surface borehole and detection of EH-4 continuous conductivity profile instrument, the overburden failure features and water filling states before and after N1S1 Coal Face mining in Daping Coal Mine were detected, and the deformation and failure features of overburden were retrieved and simulated by using RFPA2D Software. The results show that the permeable fractured zone is developed in the vertical pressure-relief and horizontal tensile zone of rock stratum above goaf, while the top interface depth is 220.92 m, and the average flushing water leakage in borehole is 0.50~0.71 L/(s·m). Meanwhile, the weak water-bearing section in the lower part of Cretaceous sandstone and sandy conglomerate confined aquifer is located in the fracture zone, while the rock strata below the depth of 200 m are in the state of water filling, and the apparent resistivity is 20~40 Ω·m. In addition, the rock strata which are above the permeable fractured zone, and below the depth of about 120 m, are in the states of vertical pressure-relief and horizontal compression, as well as bed separation development, and no water filling. Thus, the coal mining under the reservoir is safety and reliable.
