极近距煤层开采工艺研究

Study on Mining Technology of Contiguous Coal Seams

在极近距煤层开采过程中,由于特殊的地质条件,在开采过程中容易出现开采困难等问题。当工作面煤质比较坚硬、空间狭小时,采煤机割煤困难,严重降低了生产效率。因此,需要进一步提高极近距煤层的开采工艺水平,总结极近距煤层的特点,针对生产困难环节改进防护措施,提高各个生产环节的可靠性,从而提升开采效率。

During the mining process of contiguous coal seams,due to the special geological conditions,problems such as mining difficulties are prone to occur during the mining process.When the coal quality is relatively hard and the space is small in the working face,the coal mining machine is difficult to cut coal,which seriously reduces the production efficiency.Therefore,it is necessary to further improve the mining technology level of contiguous coal seams,summarize the characteristics of contiguous coal seams,improve the protective measures for the production difficulties,improve the reliability of each production link and thus improve the mining efficiency.
