The results show that: 1) the theoretically calculated maximum damage depth of the bottom plate is 27.5 m, and its layer is located above the Austrian ash aquifer, which has the danger of water breakout;2) the drill hole peeping at the bottom plate of the working face shows that the depth of the bottom plate fissure development reaches 26 m, and the integrity of the water barrier layer has been damaged, so there is the risk of water breakout;3) for the microseismic monitoring of the anomalous area, the bottom plate of the return air downstream channel occurs in the field with a one-week lag, which shows that microseismic monitoring events may reflect the water breakout of the underground. This shows that the microseismic monitoring events can reflect the changes of the underground flow field, which can provide a reference basis for the early warning of water breakout. The research results can provide reference for the prediction of sudden water hazard.展开更多

In this study, the author intends to focus on two phases where the spectators are turning voyeurs without their consent. In the first phase, the study reveals the process where film influences voyeuristic behavior. The urge to explore others' private matters starts through the way film reflects, reveals, and even plays on the straight, socially established interpretation of sexual difference which controls images, erotic ways of looking, and spectacle. Several voyeuristic means in films pursue set formation, and they all persuade the viewer to identify with the male character by allowing the viewer to see what he sees through different voyeuristic means. The use of devices as a telescope, magnifying glass, and keyholes is the motivation for the close-up shots. They turn the viewer into a participant and spectator and allow the viewer to look at previously unseen and hidden details, but they do not let the viewer become totally a part of the action. In this study, films like Peeping Tom and Sliver are analyzed to understand big screen voyeurism. In the second phase, this study presents the voyeurism initiated by television programs such as reality shows, "soap operas", daytime television, talk shows, real life documentaries, and "docudramas". At the pinnacle, there are the government, police, and the employers who are assisting to produce a new "watched" culture with the use of closed circuit TV devices. Some camera operators are known to have made "greatest hits" tapes and other material captured on CCTV has become the footage used to create television programs for entertainment purposes. Thus, they are influencing public voyeurism. Programs like "Big Daddy", "Big Brother", and "Big Boss" are disclosing personal activities of the characters through hidden cameras. They are considered as soft-core pornography on mainstream television and satellite channe展开更多
