Ashwin Mankading Buttler not in spirit of game: MCC after reviewing footage

(@IPL Photo)HIGHLIGHTSR Ashwin run out Jos Buttler at the non-striker’s end during RR vs KXIP in IPL 2019This is the first instance of Mankading in the history of IPLMCC had earlier said that Ashwin’s act was within the laws and not against the spirit of the gameRavichandran Ashwin’s recent ‘Mankad’ dismissal of Jos Buttler in the Indian Premier League was not “within the spirit of the game”, the Marylebone Cricket Club (MCC) has said after reviewing footage of the incident.The MCC, custodian of cricket’s laws, had earlier said the decision could have gone either way depending on how ‘the instant when the bowler would normally have been expected to release the ball’ is interpreted.”Having extensively reviewed the incident again and after further reflection we don’t think it was within the spirit of the game,” Fraser Stewart, the MCC’s manager of the laws of cricket, told the Daily Telegraph.Kings XI Punjab captain Ashwin sparked a chorus of disapproval from fellow players and pundits after running out Buttler when the Rajasthan Royals batsman was backing up at the non-striker’s end instead of completing his delivery.The dismissal, named after India bowler Vinoo Mankad who ran out Australia’s Bill Brown in similar fashion in 1947, is permitted under cricket’s laws but viewed by some as going against the spirit of the game.The MCC changed its stance because Ashwin paused after his delivery stride and waited for Buttler to leave the crease before whipping the bails off.”We believe the pause was too long between the time Ashwin reached the crease and the moment it was reasonable to expect the ball would be delivered,” Stewart added.”When Buttler could have reasonably expected the ball to be delivered, he was in his ground. We now think at the key moment Buttler was in his ground.advertisement”Buttler, it’s fair to say, did not make a concerted effort to get back into his crease after Ashwin had delayed his delivery, and didn’t help himself in that respect.”Stewart said non-strikers should stop trying to gain an advantage by backing up before the ball was bowled.”It’s also unfair and against the spirit of cricket for non-strikers to leave their ground too early,” he added. “All these debates wouldn’t be necessary if non-strikers remained in their ground until the ball is on its way down the pitch.”Also Read | Mankad effect: R Ashwin trolled after leaking 47 runs in 4 overs vs KKRAlso Read | Once Mankaded by Kapil Dev, Peter Kirsten feels Ashwin’s action was below the beltAlso Read | Did Ashwin watch Lagaan before Mankading Buttler?Also Read | When R Ashwin Mankaded Sri Lankan batsman in 2012, Sehwag and Sachin withdrew appealAlso Read | Ashwin Mankading: Stop judging him already, he’s not a disgraceFor sports news, updates, live scores and cricket fixtures, log on to indiatoday.in/sports.

Equotip greatly assists geometallurgical investigations at Bowdens silver project

first_imgAMC Consultants has been engaged by Silver Mines Ltd to complete aspects of a Value Engineering Study (VES) for the Bowdens silver mine in New South Wales, Australia. The package of work is intended to update and improve the understanding of the geological, metallurgical, geotechnical and mining engineering components of the previous project studies. The work will lead into a DFS and, ultimately, into development of the project. As part of the VES, AMC proposed to implement a geometallurgical program to improve the characterization of the processing behaviour of the ore. Ian Lipton, AMC’s Corporate Consulting Manager/Principal Geologist explains that “part of this program was a trial of the Equotip rebound hardness tester to measure the hardness of the drill core, and for comparison with the results of conventional comminution testing. The Equotip is a small, portable device that has been demonstrated to be an effective tool for orebody hardness measurement. “It consists of a pen-like impact device containing a small, spring-mounted, tungsten carbide–tipped spear. The spear is released and passes through the pen, strikes the sample and rebounds. The impelled velocity of the spear is measured when the permanent magnet, built into the spear, passes through a wire coil near the base of the pen. The device also measures the velocity of the spear as it rebounds from the test object. The hardness of the material (Leeb hardness) is calculated as the ratio of the rebound velocity and the impelled velocity, multiplied by 1,000. The method is non-destructive and individual measurements only take a few seconds.“After completing orientation tests, Equotip measurements were conducted on the core remaining from six intervals on which standard comminution tests had been carried out in 2012. The objective of the tests was to determine whether a useful correlation could be made between Equotip hardness measurements and the results of the earlier SMC and Bond work index tests. All measurements were carried out on quarter core-in-core trays positioned on a heavy wooden workbench in the core shed. The hardness of the core was measured with the Equotip at approximately 2 cm intervals over the 10 m – 15 m intervals corresponding to the 2012 comminution test samples. The hardness measurements were averaged over each metre and were relatively consistent within each intercept. Scattered very low values appeared related to small areas of alteration or imperfect contact between the instrument and the core.“The results were plotted against the comminution test results from 2012. The Leeb hardness measurements show remarkably strong correlations with Bond ball work index (BBWi) and the A x b parameter derived from SMC Tests®. The BBWi provides an estimate of specific energy consumption in a ball mill and the A x b parameter, which has no formal units, is a rock breakage parameter that is valuable for semi-autogenous grinding (SAG) mill design. An exponential model provided an excellent fit with R-squared values close to 1.“The tests demonstrated that the Equotip can be used to map hardness variations in drill core at a scale that can be correlated against comminution test data and geological logs. At a cost in the order of A$5/m, the Equotip is much less expensive than conventional comminution testing and the tests are non-destructive. Logging of all the drill core from the deposit is therefore a cost-effective option. The tool has the potential to provide a much-improved estimate of power consumption, mill throughput, and operating costs for the Bowdens project. “As well as having application in feasibility studies, hardness mapping using the Equotip, could potentially be applied to many operating mines where the milling circuit struggles to handle fluctuations in ore hardness. Variability in the quality of mill feed may reduce throughput, increase recirculating load, and increase power consumption. Equotip testing could be used to map ore hardness in sufficient detail that Bond work index or A x b could be estimated on a block-by-block basis in the mineral resource and ore reserves models. Comminution characteristics could then be included in block value estimation, and mine scheduling, resulting in reduced variability in the hardness characteristics of the run of mine ore, and consequently higher mill throughput and/or lower energy consumption.last_img read more
