【摘要】：近年来我国对煤矿不断开采，，矿坑不断变深，边坡也越来越突出，其中露天煤矿的事故中很多都是由于边坡的变形和滑坡造成的。要想保证煤矿的所有生产工作都能在安全有序的环境下进行，对其进行安全有效的监控是很必要的。GPS技术由于具有定位精度高、易于实现等优点，被应用于各种监测技术中。将GPS定位技术应用于边坡监测工作中，可以获得很高的监测精度，更易于实现系统的自动化。本系统利用GPS导航定位信号为基本的监测数据，根据测相伪距观测方程利用载波相位差分的原理进行定位。采用处理软件对其进行数据解算，提出了利用载波相位求差法来进行周跳的探测和修复，利用VTEC模型进行电离层误差的修正，利用Black模型进行对流层误差的修正等，提出了利用霍夫曼编码来进行GPS数据的压缩。最后确定安装在煤矿的各监测站的监测点的位置信息，进一步形成整个煤矿的信息集成平台。当出现异常数据时，系统能够自动及时地进行报警。与以往的监测技术比，该系统自动化集成度高，定位精度高，反应灵敏，数据可靠，可用于长期空间结构监测和状态评估。
[Abstract]:In recent years, with the continuous exploitation of coal mines in our country, the pit is getting deeper and deeper, and the slope is more and more prominent. Many accidents in open pit coal mine are caused by the deformation of slope and landslide. In order to ensure that all production of coal mines can be carried out in a safe and orderly environment, it is very necessary to carry out safe and effective monitoring and control. GPS technology has been applied in various monitoring technologies because of its high positioning accuracy and easy realization. The application of GPS positioning technology in slope monitoring can obtain high monitoring accuracy, and it is easier to realize the automation of the system. The system uses the GPS navigation and positioning signal as the basic monitoring data, and uses the principle of carrier phase difference to locate according to the pseudo-range observation equation. The method of carrier phase difference is used to detect and repair the cycle slip, the ionospheric error is corrected by VTEC model, and the troposphere error is corrected by Black model. Hoffman coding is used to compress GPS data. Finally, the location information of the monitoring stations installed in the coal mine is determined, and the information integration platform of the whole coal mine is further formed. When abnormal data appear, the system can automatically alarm in time. Compared with the previous monitoring technology, the system has high automation integration, high positioning accuracy, sensitive response, reliable data, and can be used for long-term spatial structure monitoring and state evaluation.
