and adjust a blast from design through to implementation. It pro- vides features to validate and improve the entire blasting process. Feedback and monitoring can now be directly used to continuous- ly improve the blasting process, creating smarter designs. The integration of Leica's J2drill format now allows designs to be exported as flat file to fleet management systems for drills. Once drilled, the actual locations can be loaded and updated against designed locations. This benefits the charging process and helps to adjust the blast design based on the actual hole location. It also provides a safety mechanism to avoid drilling bootlegs. The introduction of charging allows holes within a pattern to be attributed with explosive information. This is supported by a configurable consumable library, where blasting consumables and related properties can be entered and managed. Once sup- plied, the consumables, namely explosives, detonators, delays, cord, booster, and stemming, can be selectively used to create custom blasting templates. Once the blast has been charged, the blaster can visualize and animate the timing contours to fur- ther optimize fragmentation, control the blast movement, and minimize dilution. www.hexagonmining.com Hydraulic Hose The XCP4 hydraulic hose is designed to withstand constant pressure of up to 4,000 psi. The combination of the high-pres- sure capabilities along with its superior abrasion-resistant cover gives the user a solid reliable performer, according to ContiTech. The XCP4 hose meets the Mining Safety and Health Administration (MSHA) flame resistance designation, has excel- lent impulse performance and flexibility, and meets SAE 100R19 and ISO 11237 standards. The inner tube is constructed of nitrile rubber and is reinforced with two braids of high-tensile steel wire. The cover is manufactured with oil and weather-resistant synthetic rubber, giving it superior abrasion properties. The hose can withstand temperatures from -40°F to 212°F. www.contitech.us Geosynthetic Ballast System Huesker announced the availability of its SoilTain Protect geo- textile system. The patent-pending geosynthetic ballast mat- tress is constructed of interwoven geotextile tubes to form homogenous panels. These durable mattresses can, in most instances, be filled with site soils or wastes, thereby offering a beneficial reuse option for site materials and reducing the need for special fill. The system also eliminates the need to construct traditional aggregate covers for liner ballast. The acquisition and place- ment of those traditional covers is both expensive and the source of significant damage risk to a lining system. More than 70% of lining systems that are damaged prior to beginning their service lives suffer that damage during cover placement. Heavy equipment, normal cover soil/aggregate construction activity, and angular and coarse fill are the primary sources of this dam- age. With a geosynthetic approach, all of that damage risk may be eliminated. For the mining field, which uses roughly 40% of the world's annual production of geomembranes, this offers a number of advantages. Many of the lining systems in mining must be at least partially exposed to perform optimally. Some of the largest of these applications include heap-leach pads, operational water and wastewater cells, processing pits, pregnant liquor trenches, and tailings and ash storage ponds. Frequent access and filling or removing of the contained material is required. In all of these areas, the integrity of the lining system can strongly impact the site's economical and environmental performance. SoilTain Protect is targeted to improving the performance of the mining industry's high volume of liner designs. And, since mines are frequently situated in remote areas with limited access, and with very large spaces being lined, a lightweight, easy-to-transport geotextile system offers faster, more efficient installation of ballast. www.huesker.com Hydraulic Cooling Fans Cleanfix North America launched its intelligent hydraulic cooling fans used to prevent problems associated with engine overheating and inefficiency. The company now offers the standard reversing fan with hydraulic actuation (HSCSeries) in addition to the stan- dard reversing function, the thermal-controlled variable blade pitch controlled fan (HVP-Series with wax elements) plus a fully electronically controlled Hytronic fan (HT-Series). The latter con- trols the exact blade angle and the cooling performance. www.cleanfix.org November 2015 www.coalage.com 51 p r o d u c t n e w s c o n t i n u e d
