In another shield, the sensor is also mounted in a different place. The steel structure has different oscillation modes. Between 9:26 and 9:32 it can be seen in the film that rocks had caused the shutter to close. During this period a horizontal, dark blue to black structure can also be seen here at first.
Strong green areas between the resonance bands mean sliding coal.
Blue to black horizontal bands outside the resonance lines mean an interrupted coal flow.
In this graph the coal flow ends at 9:35min. The shutter was closed here. The coal flow was, however, quite sparse beforehand. Frequent, individual rocks can be clearly seen.
The results from the third shield monitored are more comparable. They also begin with a strong flow of coal.
Right at the beginning there are also a lot of heavy impacts from rocks. The coal flow in this shield was consistently sparse. The shutter was open for a relatively long time.
A sparse coal flow continued without an increa

在另一项屏蔽，传感器也安装在不同的地方。钢结构具有不同的振荡模式。 9时26分和9点32分之间，可以看到电影的岩石造成了快门关闭。在此期间的水平，深蓝色黑色结构也可以看出在这里第一次。
强大的绿色地区之间的共振带平均滑动煤。
蓝黑色横向带以外的共振线意味着中断煤流。
在此图的煤流结束于9时35分分钟。快门是在这里结束。煤流，然而，很稀疏事先。频繁发生，个别岩石可以清楚地看到。
结果从第三屏蔽监测更具有可比性。他们还开始与一个强大流煤。
开始时，有权也有很多沉重的影响岩石。煤流在这盾构始终稀疏。快门开放供相对较长的时间。
稀少的煤流继续不增加岩石被声响。
频率分析尤其是取决于参数选定。这清楚地显示在下面的图表：
频率分析，在2000年开展做了类似的方式，但使用不同的参数。
此设置显示不同的图片。较低的频率增加所造成的岩石这里。
可能的理论不同的声音事件
的方向的煤岩是有重大影响的类型的影响。噪音的产生还受到规模的任何可能的蛀牙和进展的突破边缘的煤和顶板。在2000年，我们能够计算的突破性进展边缘的帮助下，教授Veksler的理论和地质材料参数提供给我们。
上图中显示了我们的假设条件下的地质力学计算打破边缘的煤炭和/或岩石。数字1至3显示继续崩溃消失
煤和顶板。
这些理论结果符合在一定程度上与现实。在煤矿井下的访问于2000年8月，我们还试图见煤开始崩溃。打破边缘有时候可以看到之间的盾牌。这是典型的这个开始之间的两条腿（从而使执行四条腿的盾牌多余） 。
我们如何看待国家的打破前在采矿
第一素描显示盾构装有四条腿。打破前煤炭开始在中东之间的两条腿。这是煤的重量打破了屋顶收集的空防御。
