跟据2005─2009年期间煤矿钻孔与凿岩机械安全标志产品准用证及其生产企业基本状况,分析了产品发展的变化趋势。目前,各类煤矿钻孔与凿岩机械生产企业达200多家,获安全标志准用证700多份。煤矿钻孔与凿岩机械90%以上的产品,用于煤矿锚杆支护、瓦斯治理、井下采掘和放顶爆破,其中,煤矿专用产品又占85%以上。各种类型产品中,手持式电钻的市场急剧收缩,已逐渐被手持式气动钻机替代;电动锚杆钻机和电动凿岩机已被淘汰,气动锚杆钻机以及各类气动回转式钻机、液压坑道钻机和液压钻车发展较快。分析认为,锚杆支护和瓦斯治理使用的钻孔与凿岩机械将进一步发展,特别是锚杆钻车、深孔钻车、钻装锚机组和履带式液压坑道钻机等机械化设备将大力发展;液压凿岩机与液压掘进钻车是岩巷机械化的主要发展方向;气动钻孔与凿岩机械将长期存在;煤矿用回转钻具与锚杆支护用钻具有广阔市场。
According to the 2005-2009 coal mine drilling and drilling safety signs and products approved the basic status of the manufacturer, the trend of product development trends. At present, all kinds of coal mine drilling and drilling machinery manufacturing enterprises reached more than 200, access to safety signs permits more than 700 copies. Coal mine drilling and drilling machinery more than 90% of the products for coal mine bolting, gas treatment, underground mining and blasting, of which coal mine products account for more than 85%. Among the various types of products, the market for hand-held drills contracted sharply and were gradually replaced by hand-held pneumatic drills; electric anchor rigs and electric rock drills have been phased out, pneumatic bolting rigs and various types of pneumatic rotary drills, hydraulic tunnel drills and Hydraulic drilling car developed rapidly. The analysis shows that the drilling and drilling machinery used in bolt support and gas treatment will be further developed. In particular, mechanical equipment such as bolt drilling rig, deep hole drilling rig, drilling anchor assembly and crawler hydraulic tunnel drilling rig will be greatly developed. Hydraulic rock drills and hydraulic drilling vehicles are the main development directions of rock mechanization. Pneumatic drilling and rock drilling machinery will exist for a long time. The rotary drilling tools and bolt support drilling tools for coal mine have a broad market.
