Calculating coal cubic metres

发电是国家经济增长和福祉的最关键组成部分之一。由于经济的加速扩张和全球能源需求的增加，印度是世界上增长最快的能源市场. Although the power sector is diversified in this South Asian country, 62 per cent of India's electricity demand is met through the country's vast coal reserves.

Sembcorp, a leading energy, water and marine group operating across five continents worldwide, entered the Indian energy market in 2010. The company is now responsible for thermal and renewable assets accounting for more than 3,500 megawatts of power capacity in operation and under development in seven states. As part of Sembcorp, Thermal Powertech Corporation India (TPCIL) operates a1,320-megawatt coal-fired coastal power plant in India.

TPCIL的热电厂专家在过去的常规测量方法中使用，以找出煤桩的坐标和形状。每个季度对煤炭存储场进行调查以进行身体验证是一个巨大的挑战。使用Leica Nova MS50多阶段，测量煤炭桩的确切特征的挑战属于过去。

用点云扩大可能性

在3D环境中捕获现场条件是计算量并确保直接在现场最佳控制的最有效方法。该公司使用世界上第一个自我学习的跨越，捕获了股票的准确概况和数量，并在和解过程中验证了数量。

体积准确性的较小变化将导致物理库存数量的煤炭偏差和吨偏差。因此，测量中的准确性是捕获煤炭堆堆的剖面量时的一个重要好处TPCIL。

“We choose Leica MultiStation MS50 instead of a total station because we were able to achieve the accurate volume of the coal stock yard, and the report generation process is easier using Leica Infinity software. Time and cost saving was one of the main factors in this project. Optimised coal volume calculation can be achieved using the MS50,”TPCIL运营助理经理Nandagopal Kesavan说。

The physical verification survey of approximately 600,000 – 800,000 tonnes of the coal storage yard used to take seven to 10 days with conventional surveying methods. Using the MS50, the same work can be done intwo days. Surveyors were able to see all setups merged flawlessly directly on the unit and determine the scan quality in the field right on the instrument.

Experts processed the information with Infinity geospatial software, allowing to work with the scanned point data and manage data in the 3D viewer.

一项持续的工作

煤炭调查项目始于2015年7月，每季度每年都在继续。TPCIL从国际和国内煤矿接收煤炭，并进行煤炭库存物理验证测试至：

• Ensure book stock and consumption of coal is matching with the physical stock available on date;
• 即使书籍股票足够多，也可以在物理上可获得足够的国内和进口煤炭库存；
• Calculate the amount of coal loss during the conveying by matching the ship vessel draft survey report with the physically verified stock available for the ship consignment.

呈规则提供了一个technical solution optimised for coal volume calculation为该项目和公司开发。

鉴于MS50的成功，Sembcorp购买了另一项MS60以进行煤炭量估算。
