近年来,我市地方煤矿经过多年强化开采后,面临的困难和问题越来越突出:一是部分矿井储量枯竭;二是多数矿井已从条件较好的上组煤转入受水威胁的下组煤、“三下”压煤、极薄煤层及各种呆滞煤量开采;三是开采水平逐年加深,提升环节增多,通风管理复杂,顶板压力增大,采掘支护困难。为不断增强地方煤矿发展后劲,自1988年以来,我们坚持依靠科技进步,走内涵发展道路,积极组织开展科研攻关,推广应用新技术、新工艺,取得了明显效果。我们的主要做法是:
In recent years, local mining in our city after years of intensive mining, the difficulties and problems are more and more prominent: First, part of the depletion of mine reserves; second, most of the mine from the better conditions of coal into the water under the threat of Group coal, “three under” coal, very thin coal seam and a variety of sluggish coal mining; Third, the level of exploitation deepens year by year, increasing links, ventilation management complex, roof pressure increases, supporting excavation difficulties. In order to continuously enhance the development potential of local coal mines, we have been making remarkable achievements in relying on scientific and technological progress, taking the road of connotation development, actively organizing scientific research and popularizing new technologies and techniques since 1988. Our main approach is:
