The Deployment of Garmin GPSMAP 66s For Collecting Points And Stakeout In The Mining Site

Introduction

The Singareni Collieries Company (SCCL) is a government-owned coal mining company in Kothagudem, Telangana. The company takes its legacy of operating almost close to 48 coal mines which come under the category of underground and opencast. These coal mines are spread across the 6 districts of Telangana such as Komaram Bheem, Mancherial, Peddapalli, Prof. Jayashankar-Bhupalpalli, Bhadradri-Kothagudem which are in Khammam.

The Requirement

The management of SCCL, wanted to have a hand-held Global Positioning System (GPS) and GLONASS High-sensitivity receiver with certain specifications such as accuracy-which is less than 3 meters, Display Size- 3 inches, Internal Memory of 2000-waypoints/favorites/locations of 200 routs. Track log 10000 points, 200 saved tracks, Data storage- 2GB, Position format – Decimal degrees (Lat./Long.UTM/ups), WATER RATING – IPX7 etc. The most important attribute is that it should be completely functional even during the harsh environment that is the reason it is suitable for the mining site.

The Solution

We offered Garmin GPSMAP GPS + GLONASS + GALILEO High-sensitivity receiver which is Premium GPS Handheld with BirdsEye Satellite Imagery Subscription having positional accuracy of +/-2m, Large, 3” sunlight-readable color display for easy viewing.

In addition to the multi-GNSS support system, the GPSMAP 66s provides the Altimeter, Barometer and Compass (ABC) sensor capabilities to track your work record and store all the waypoint/favourites/locations, track log and routes in the 16 GB memory storage.

The device comes with more additional features which includes the position format-decimal degrees with reference to (Lat./Long.UTM/ups), WATER RATING – IPX7 means that the light is waterproof when submerged in water at a depth of one meter, for 30 minutes,ruggedness for thermal, shock and water performance, Wi-Fi, Bluetooth and ANT+ etc which is perfectly suitable as per the requirement of the department.

The Results

The offered solution helped the department to collect points with the positional accuracy and could help them with future references to perform the stake out.

Leica DISTO D110 Used In SCCL Mines For Faster And Reliable Measurements

Introduction

The Singareni Collieries Company (SCCL) is a government-owned coal mining company in Telangana, India, which is located at Kothagudem, and takes its legacy in operating close to 48 mines which come under the category of both underground and opencast and this is being spread across 6 districts in Telangana viz. Komaram Bheem, Mancherial, Peddapalli, Prof. Jayashankar-Bhupalpalli, Bhadradri-Kothagudem which is in Khammam.

The Challenge

In the previous instance, when some of them tested the previously used measurement tool underground, many of these devices exploded because they used to carry the alkaline battery to power the device. As one can understand that the temperature in the underground is always high and the usage of an alkaline battery is not suitable.

The department instead wanted to replace these alkaline-fed batteries to the lithium-ion battery,  which is much more compatible with the device, and was much safer to be used for a prolonged time.

The department of excavation of coal mines were in a dilemma of finding the laser distance measurement of 50 meters underground in the coal mine site. They wanted a device with comes with additional features such as the accuracy of less than 5 mm, IP54 and further to this, the device which could aptly take the measurement in units of meters (mm), inches (in) and feet (ft), and the device should weigh less than  250 g.

The Solution

In view of the prevailing situation of the underground coal mine, we offered Leica Laser Distance Meter (DISTO D110), which is perfectly calibrated to measure the distance at 60 m range, and comes with a deviation accuracy of 1.5 mm, plus additional features such as accuracy of +/- 5 mm, IP54 rating, which indicates the device is protected against dust & splash.

One more attribute is that the device is quite capable of generating the measurements of units within mm/in/ft and comes with a weight of 92g. The device becomes absolutely compatible with the AAA lithium-ion battery and with the charger.

The Results

The implementation of the Leica Laser Distance Meter (DISTO D110) with the compatible AAA Lithium-ion battery, the measurement of the coal extracts were made prolifically well and the entire device was quite efficient and the device got safe-guarded against any sort of explosion. Above all, the device was able to vehemently withstand the internal explosion.
