Only mining thickness factor is considered in the experiential formula,in fact,the mining depth,the length of working face and the dip angle of coal bed should be included.

传统的经验公式对导水裂隙带的估算值考虑了采高一个因素，而实际上导水裂隙带的发育高度还与采深、工作面长度、煤层倾角等因素有关。

With the technique, the glass composition is optimized, the operation temperature of the synthetic glass is increased, the inwall structure of the channel is improved, and the open aperture ratio reaches 65%～70%.

它优化了玻璃成份，提高了玻璃的工作温度，同时还改善了通道内壁工作面结构，且开口面积比达到65%～70%。

Based on modeling test in water tank, this paper employed three different iron blocks to model water-bearing bodies and enclosed plastic pipes or rounded wood strips to model roadways. It gave physical modeling of water-bearing bodies in the working face floor with parallel Bipole-Dipole method, made analysis on the character of electrical field and the law of apparent resistivity changing when the low resistivity abnormity bodies were placed flatly close to water level under semi-space condition and were placed flatly, vertically or aslope to the water level under whole-space condition.

本文以三种不同规格的铁块模拟含水体，以密闭的塑料管或木块条模拟巷道，通过水槽模拟实验，采用平行双极—偶极法进行了对工作面底板含水体的物理模拟，分析了低阻异常体铁块在半空间条件下近水面水平放置以及全空间条件下水平、垂直和倾斜放置时的电场特征和视电阻率变化规律。

In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward.

在后退式采煤工作面运输巷中，当转载机推移到其拱桥段全部与带式输送机机尾段搭接叠的极限位置时，可伸缩带式输送机缩短一个搭接长度，带式输送机的机发展部移置到转载机卸载机头下方，转载机又可随工作面的推进而向前推移。

However, the coal bunker channeling warehouses in China coal mine accidents occur frequently.

它可以有效地提高工作面采掘设备的利用率，充分发挥运输系统的潜力，保证连续均衡生产。

Kinematics from the speakers, it is stable, which is the optimal shield in the box-stent and the stent Crib 1:00, Leung also cover is closed goaf, so as to prevent the rock into the broken roof support Face.

从运动学讲，它是稳定的，这是掩护式支架最优于框式支架和垛式支架的一点，掩护梁也完全封闭了采空区，从而能够防止破碎顶板岩石掉入支撑工作面。
