For those mines adopting the sublevel caving method, the large structure parameters of the natural lay are not suitable for the ore drawing in transition sublevel process.

采用无底柱分段崩落法回采的矿山，在向大结构参数的转变过程中，正常布置的大结构参数不适用于过渡分段的放矿。

A computer-aided technical management for sublevel caving is established and its structural design, compositions and functions are introduced.

介绍了一种适用于无底柱分段崩落法的计算机辅助技术管理系统的结构设计、系统组成与功能等。

This paper briefly describes topography and geology conditions of the Dan-jiangkou reservoir, and analyses the influential factors and forms of bank caving, and adopts engineering geologic analogy method to predict the influential area and difficulty degrees of bank caving on the basis of wide investigation.

为了预测水库坍岸范围和发生坍岸的难易程度，对丹江口水库的地形、地质条件和坍岸的影响因素和型式进行了分析。

The high-rise wood piled wharf in Qingdao harbor was constructed from 1901 to 1906. The deformation on the surface and quay wall of the wharf and bank caving happened between whiles.

但是其安全运行的问题日益突出，事故时有发生。青岛港木质高桩码头建于1901～1906年，目前，码头表面和岸壁变形及局部滑塌偶有发生。

The lower part of the slope locates in water level change belt of the yangtze river Three Gorges reservoir; predicted width of bank caving will be up to 190 m~ 300 m.

斜坡下部位于长江三峡水库水位变动带，预测坍岸宽度可达190～300m。

The primary target of the monitoring is to dynamically determine the developing regularity, and heights of the" two zones"( caving zone and fractured zone) in roof rocks.

该监测的主要目的是动态测定煤层开采过程中顶板岩石两带（冒落带和裂隙带）的发展规律和高度，以指导相邻采区留设合理的防水或防砂煤柱。

The results show that, the overlying coal-rock mass is integrally bending and sinking, without forming any caving zone and the obvious fault zone.

结果表明，在极薄保护层钻采过程中上覆煤岩体产生整体弯曲下沉，没有冒落带和明显的断裂带。

Therefore, it is foundation of coal mining and design to provide accurate information of caving zone and water flowing fractured zone before and after mining.

准确地提供采煤前后顶底板岩层冒落带高度、导水裂隙带高度及其形态变化等信息，是安全采煤可行性研究和设计的基础。

The height of the watering fissures is 21.5m because the height of caving zone is about 10m after the mining of all the 3 seam ( 4 layers), and the result basically accord to the result of theoretic calculating and numerical simulation;

3煤层全采后（4个分层）垮落带高度为10m左右，导水裂隙带的高度为21.5m，与理论计算和数值模拟结果基本一致；
