技术白皮书通过GPS使用提高非公路卡车安全（Dagdelen和涅托- 维加，科罗拉多矿业学院）如果GPS技术融入他们的机器中，可以减少在露天矿山中设备操作人员的死亡。
目前，GPS已成为在卡车调度系统和实地测量的标准组件。
特别是在大型露天矿山，坑和转储地图正在被使用时，可以直接传送到卡车上的单板计算机中。
与差分GPS车载设备相比，可以迅速确定一个给定精度小于一米的卡车的精确坐标，并评估一个给定的卡车是否危险接近倾销边缘的一个废料堆和大量倾销的任务有关的致命交通意外发生。

准确的选择性开采矿化视野2。
准确地找到煤剥离操作的矮墙面糊线，从而减少overdig，或失去煤3。
如加载爆炸地区或危险区域，准确地表述旧地下运作4。
创造更长椅，从而减少了卡车的周期时间和卡车上的磨损，减少长凳上推土机及平地机时间一个典型的例子是科林斯维尔煤矿，在北昆士兰的Thiess承包商拥有和经营斯特拉塔煤炭。
引入一种导航系统、三坑里装有150万立方米的挖掘机翻土，表土显示0.99%的平均overdig和underdig 0.93%。
安装GPS指导的挖掘机挖的搬到12坑钱的表土达320万立方米,显示平均3.86%的overdig和1.82%的underdig。
减少overdig 足以支付系统在几个月。

它有15个容量范围从8到14立方米，85吨容量的50辆卡车和30 辆卡车120吨的卡车挖掘机的车队。
OITDS系统涵盖整个挖掘机和卡车车队。
该系统的概念在1999年和2002年9月实施。
最好是在这本书中扩展。
GPS推土机机指导（APS 2003年3月）的利益纳入矿山机械GPS导航系统的主要好处有两个：a）信息生成能够帮助操作者矿体定位与机器或卸泥区的位置的位置。
b）信息可以发回的实时控制中心，以评估机做什么，从而提高生产效率和质量，以及实时的基础上。
具体的GPS矿山设备的好处包括：A）推土机。
没有实地调查的需要完成土方工作可以做，可以实现复杂的剥离设计，提供高效的材料为最佳运动GPS操作指导到哪里移动的物质和推多远。
B）播种机。
挖掘设备，从钻井产生的信息，可以登录到GPS系统。
C）液压挖掘机可以用挖掘机铲斗的位置来确定的长椅上设计的档次。
此外，该设备可以做选择性开采，特别是在有没有区别的视觉差异，特别是在氧化黄金业务，矿石和废石。
生产率的提高将来自除其他外，消除错误和返工，消除实地调查，回收率高和较低的宝贵矿产稀释，并增加操作者的信心。
Authors: Jack CaldwellSUMMARYThis review describes the use of Global Positioning System (GPS) in Mining including Mine and Ore Body Exploration, Development, Production, Closure, Reclamation, and Mine Title Application in British Columbia. The review also examines and evaluates web sites that specialize in GPS Technology, Mine Application of GPS, GPS Equipment Suppliers, and Consultants providing services in mining-related GPS Applications.PAPERSImproving Safety of Off-Highway Trucks through GPS (Dagdelen and Nieto-Vega, Colorado School of Mines) Fatalities among equipment operators in open pit mines can be reduced if GPS technology is incorporated in their machines. Currently, GPS is becoming a standard component in truck dispatch systems and field surveying. Especially in large open pit mines, pit and dump maps are being made in real time and can be transferred directly to the on-board computers of the trucks. With differential GPS equipment on board, one can quickly determine exact coordinates of a given truck with accuracy of less than a meter and evaluate whether a given truck is dangerously close to the dumping edge of a waste dump. Fatal accidents related to dumping tasks are occurring in significant numbers.Applications for GPS on Shovels and Excavators (Seymour, C.) With high precision guidance systems for shovel and excavator buckets, the following benefits are also enumerated:1. Accurate selective mining of mineralized horizons2. Accurately finding the low wall batter line in coal stripping operations, thus reducing overdig, or lost coal3. Accurate representation of hazardous areas, such as loaded blast areas or areas underlain by old underground workings4. Creating more even benches, thus reducingtruck cycle times and wear and tear on trucksand reducing dozer and grader time on benchesA case in point is the Collinsville Coal Mine,owned by Xstrata Coal and operated by ThiessContractors in northern Queensland.Following the introduction of a guidance system, three pits containing 1.5 million cubic meters of excavator-dug overburden showed an average overdig of 0.99% and underdig of 0.93%. Overburden which was moved in 12 pits dug prior to the installation of GPS guidance amounted to 3.2 million cubic meters and showed an average 3.86% of overdig and 1.82% of underdig. The reduction in overdig was sufficient to pay for the systems within a few months. Thiess subsequently installed guidance systems on the three other excavators at the site.The Role of High Precision GPS Machine Guidance in Mining (Seymour and Williams, 2003) GPS technology can now locate the bucket of a shovel or the blade of a dozer to within 50 mm. Other positive outcomes include precise selective mining, even when the ore is visually indistinguishable from waste; tracking grade and tonnage of every ore parcel through the mine;real-time productivity monitoring; detailed post-accident safety analysis; and tracking the movements of every piece of equipment.GPS-based Machine Guidance in the Mining Industry (Seymour, 2003)The Jayant mine handles 30 million cubic meters of mine overburden (the waste product generated during mining operations) and around 10 million tones of coal in a year. It has a fleet of 15 excavators with a capacity ranging from eight to 14 cubic meters, 50 trucks of 85-tonne capacity and 30 trucks of 120-tonne capacity. The OITDS system covers the entire fleet of excavators and trucks. This system was conceptualized in 1999 and was implemented in September 2002. It is best expanded upon in this book .Benefits of GPS Machine Guidance on Dozers (APS, March 2003) There are two major benefits for incorporating GPS guidance systems on mining machines:a) Information generated can help the operator to locate the orebody vs. the position of the machine or the location of dumping sites.b) Information can be sent back to the control centre in real time to assess what the machine has done, which increases productivity and quality on a real-time basis as well.Specific GPS benefits for mine equipment include:a) Dozers. Complete earth moving jobs can be done without the need for field survey pegging; sophisticated stripping design can be implemented that provides for the optimal efficient movement of material, with GPS guiding the operator as to where to move the material and how far to push it.b) Drills. Information generated from drilling can be logged onto GPS systems on excavation equipment.c) Hydraulic Excavators can be used to design grades on benches to determining the position of the excavator bucket. Also, the equipment can do selective mining especially where there is no distinguishing visual difference between ore and waste, especially in oxide gold operations.Productivity gains will come from, among other things, elimination of mistakes and rework, elimination of field survey, high recovery and lower dilution of the valuable mineral, and added operators' confidence.译文电子一液压集成控制的调整控制单元是根据通用标准设计的，其功能及完成的具体任务由控制中心的微处理器决定并控制。
