“We are more than ready to kick-start all the emergency works,” said Jose Assalino, Director of the International Labour Organization (ILO) office in Kathmandu.“We will build on existing progress. We have been working [in the country]. Employment and social protection is part of the priority number one of the [ILO] country-program signed with Nepal in 2013,” he added. Mr. Assalino said that the agency has been working on national employment policy and social security law in Nepal prior to the earthquake and has stayed active during the early recovery period. The country’s ILO office will stay committed to responding to whatever work lies ahead. Currently, the ILO has programmes in partnership with the Government and the World Bank in 33 districts of Nepal. These districts include all those that were most affected by the earthquake.“The ILO is working to give jobs to the people, in all those districts, to work on a permanent basis,” Mr. Assalino said in his message. “This gives us a very good platform to build the concrete actions that you want to do now to respond to the situation.” The work is more than “just short-term cash for work,” he said. The ILO’s efforts are also focused on the long-term, which means that successes will last based on a comprehensive maintenance program and better training. This will require the deep involvement of the Government at the national level and local level. He also emphasized the importance of ensuring sustainability and strong basis to upgrade activities.There are currently 69 ILO engineers in the field in 33 districts. There are also 3,200 workers in the fields, working with this 33 district administrations with staff.“We need those local administrations so it’s not something isolated in the field, an agency deploying a couple of staff to do some work in the field, we are fully integrated in the government system and this puts us in a position that I can tell you nobody else has in Nepal in this moment,” he said. On 25 April, a 7.8 magnitude earthquake shook Nepal, killing thousands while limiting access to food and leaving some 3.5 million in need of food assistance. An estimated 8 million people across the country’s Western and Central Regions are affected by the disaster, including its largest cities, Kathmandu and Pokhara.
VOD (Ventilation on Demand) has been used at Xstrata’s Nickel Rim mine with great success. “The Nickel Rim mine project has enabled unique applications of technology with the goal of improving productivity and reliability. A key example of this can be found in the newly constructed surface exhaust fan installation where innovative approaches to ventilation technology include the use of variable frequency drives, multi-fan programmable logic control (PLC) and fan starting considerations1.”XPS Process Control (together with the mine’s Engineering and Operations team) has worked diligently in the design and commissioning of the Allen Bradley (Rockwell) control system and the surface fan controls optimisation, in a layered control application approach, specifically:Basic control loop standardDesign and simulationLoop tuning of the whole control strategy (surface fans)Loop tuning of all AMS (air monitoring stations) undergroundTesting of surface fans interaction with AMS (air monitoring stations) under several different scenarios.During July and August 2010, the whole control strategy was run in automatic and cascade control mode for several hours at a time on four occasions. The control strategy here is a basic to advanced, interconnected, regulatory strategy that has been programmed in the PLCs to co-ordinate surface fans exhaust and supply fans. Use of the Simsmart OMVOD system, during one of the tests, was for controlling a flow that could not be measured.For the days tested, the exhaust fan rpm was observed to run up to 200 rpm slower, proving a realistic energy saving opportunity, or liberated capacity which can be used to drive further production, or increased productivity. The strategy was able to automatically recognise opportunities and adjust fan speed accordingly.All the PID controllers have now been tuned and, following training and robustness testing, will shortly be ready to be used in their normal operating mode (auto and cascade) – a significant step to achieving ventilation on demand.1.
