Atlas Copco launches Boomer M1 L - a new, robust single boom drill rig for low vein mining
12/8/2011
Narrow drifts with low roofs and extensive tramming adds up to a tough environment for miners as well as equipment. The new single-boom drill rig from Atlas Copco can take it in its stride - and provide added comfort for operators.
The latest single-boom face drilling rig from Atlas Copco combines extreme robustness with operator comfort. Specially designed for development and production drilling in low-to-medium height mines, the Boomer M1 L claims to be the most robust of its kind on the market.
With a height of 1.8 m, which is slightly higher than previous low profile rigs of this type from Atlas Copco, it is the ideal choice for room and pillar mines with roof heights of 2.2-2.5 m. It has an extremely strong carrier as well as oversized wheels compared to similar rigs in the range.
"This is the perfect rig for the rough and tough world of low vein mining in room and pillar operations - especially where there are long distances to be covered," says Peter Bray, Product Manager at Atlas Copco's underground equipment division.
"Typically, rigs of this type have to cover distances of six to twelve kilometers a day and that requires a machine that can really take a lot of wear and tear. The Boomer M1 L can handle this with no problem. Its strong components are built to withstand tramming on rough roadways over long periods of time."
Bray explains that the Atlas Copco designers have "married together" components and systems from existing drill rigs such as the Boomer S1 L and the Boomer M2 D in order to meet customer demands for a stronger workhorse in low roof applications.
At the same time, the Boomer M1 L also makes life a lot easier, safer and more comfortable for the operator. It has a fully enclosed, spacious and air conditioned cabin. Visibility is excellent and the environment inside the cabin is matched outside by the environment-friendly, low emission Deutz 80kW Tier 3 engine.
Other advantages include an improved flexible boom, simple controls (Direct Control System 2 - DCS 2) as well as a choice of COP 1638 or COP 1838 rock drills. The rig is also designed to be extremely easy to service to keep downtime to a minimum.
A prototype of the Boomer M1 L was successfully tested by the Polish mining company KGHM which has since placed orders for several units.

The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
