Spanish equipment & expertise.

A look at some of the hardware and services in opencast and underground coal and metalliferous mining offered to the industry internationally by Spanish companies.

ANMOPyC -- (Associacion Espanola De Fabricantes Exportadores De Maquinaria Pare Construccion Y Obras Publicas -- the Spanish Association of Manufacturers and Exporters of Construction Machinery and Equipment for Public Works) founded in 1982, has around 50 manufacturing member companies, many of which make equipment used in opencast and underground mining, quarrying and mineral processing. Such companies include Industrias Leblan (jaw crushers, trommels, conveyors); Korota (hydraulic hammers); Llamada (drill and excavator components); M. Carrera (compressors); Pro-mining (winches and transportation systems); and Rodajes (buckets and rippers, etc). Other member companies such as TAIM-TFG and Guria are considered separately below.

In recent years ANMOPyC has organised trade delegations to such countries as Chile and Mexico -- an indication that its member companies are looking to increase exports farther afield. Currently, some 60% of exports by member companies go to Europe, particularly France and Portugal. Other potential markets now being targeted are Eastern Europe and the Middle East.

TAIM-TFG offers a wide range of equipment for mining -- particularly of coal -- which is sold within Spain and in other countries. Of special interest are two new products -- the model MT 45 roadheader and the Aterbi coal cutter.

In Spain, coal mining operations are often confronted by tricky geological problems and in consequence mechanisation is often difficult and its scope limited. TAIM-TFG, with long experience in the field, had managed to develop versatile and adaptable mining equipment suited to these conditions.

A recent ambitious undertaking has been development of a coal cutter capable of mining narrow (0.7-1.1 m), hard coal seams which cannot be tackled with conventional equipment. This cutter has been designed specifically for important coal resources in the El Bierzo (Leon) coal basin. The short machine has radio-controlled cutter commands and inside the cutting drums are planetary reducers to lessen the length of the cutter. Special attention has been paid to dust suppression by high-pressure water injection.

Essentially a compact, double-ended ranging drum shearer, the machine has a cutting power of 2 x 75 kW; speed of traverse 0-6 m/min; machine body length 2,200 mm; length between drum centres 3,690 mm; and a height of 550 mm. The double bidirectional drums have a diameter of 650 mm and length 650-800 mm. The Aterbi system thus meets the requirement for a compact coal cutter able to cope with rocks up to 40 Mpa.

TAIM's MT 45 roadheader has been developed for advancing coal mine roadways of small cross-section. It can be used in room-and-pillar mining and tunnelling work in general where the ground is not excessively hard. The machine's modular design facilitates quick assembly/disassembly when it is moved to different locations in the mine. The large crawler base allows working in soft ground conditions and all electrical equipment is flameproofed for use in gassy mines. Remote control is offered as an optional extra, as is an articulated bridge conveyor suspended from a monorail and attached to the rear of the Mt 45.

Total weight of the roadheader is 15.5 t and cutting head power 45 kW. The axial-type cutting head with a maximum dia. of 0.74 m and maximum cutting height of 3.5 m has a maximum cutting width of 5.1 m. The loading system is the gathering arm type with a minimum loading apron width of 2 m. TAIM also offers the roadheader to mining companies on a rental basis, subject to certain conditions.

Union Espanola de Explosivos S.A. (U.E.E.) was founded 100 years ago with the merging of a group of small explosives producers in Spain. Currently, U.E.E. manufactures its wide variety of products in five different domestic plants and other facilities in Australia (ERT-Explosives Australia Pty Ltd) and Argentina (IQAES), and through its associates in Peru (MESUR) and Portugal (SPEL), thus placing the company among the leading group of world explosives producers.

Manufacture of explosives within Spain has paralleled the growth in the country's mining industry, providing all necessary requirements in the blasting field while keeping pace with and adopting the latest technological advances. The variety of explosives manufactured by U.E.E. encompasses different types of gelatins (Goma 2EC), emulsions (Riomex), water gels (Riogel), seismic and permissible explosives, shaped and presplitting charges and many other specialised products. All are available in different sizes and diameters ranging from 18 mm to 200 mm.

Ammonium nitrate (technical grade) is currently produced in the La Felguera facilities. Traditional Anfo and heavy Anfo are also made by U.E.E., and another line is all types of blasting accessories such as fuse caps, electric detonators (regular and permissible), safety fuses, boosters and a full range of detonating cord ranging from 1.5 to 100 g/m including its MS delays. All U.E.E. products are recognized worldwide and meet the highest quality standards.

Technical back-up is also provided by the company to assist users in solving blasting-related problems and thereby increase productivity. Special attention is given to specific problems through Rio Blast S.A., a wholly-owned subsidiary consulting company, well-versed in explosives usage and mining engineering. Blasting design of underground and opencast excavations and fragmentation studies are two areas of Rio Blast's expertise.

Explosive seismology is also covered: state-of-the-art instrumentation and analysis has been fully developed in-house by Rio Blast. The RB-1300 and RB-1400 seisomographs are designed to meet European and world standards. Environmental effects such as ground vibration and air overpressure monitoring are also dealt with. A blasting software package (Blastert) is offered.

The Alfa caplamp was developed by Suministros Adaro, S.A. to comply with European standard EN 50.033 and the Spanish UNE 22.530/85 thus meeting the requirements for use in fiery mines. Drawing on over 30 years of experience in manufacturing lighting equipment for mines, together with new technology as regards battery power storage, has resulted in a caplamp design offering optimum performance. Made entirely of tough thermoplastic resins, the Alfa caplamp is maintenance-free, robust, light in weight (use of Ni-Cd cells in the battery pack gives a lamp said to weigh 0.5 kg less than any other model currently in use); and the lamp's geometry and dimensions have been very carefully considered, so that it fits perfectly on the user's waist. Complementary with the lamps is a 14-station battery charger based on the established Adaro charging module, which can be added to according to the user's needs and which gives electronically timed and regulated charging for each lamp.

The Alfa's main features are: nominal voltage of battery pack 6 V; nominal wattage of main bulb 4 W halogenous; auxiliary bulb nominal wattage 2.4 W; weight of complete caplamp 1.8 kg; weight of battery pack 1.45 kg; and weight of headpiece 0.35 kg.
