由于传统孤岛开采技术的工作面布置不合理,导致进行孤岛开采时采煤量低。因此,对综采工作面复杂条件下孤岛开采技术展开了研究。首先,需要布置工作面并在此基础上优化工作面长度,以充分利用资源并提高采煤效率;其次,确定开采孤岛旋转半径,以便在开采过程中合理调整工作面的位置;再次,通过计算开采孤岛旋转参数,可以进一步优化工作面的旋转过程,提高采煤量;最后,利用旋转技术实现孤岛开采。实验结果表明:该方法在综采工作面复杂条件下孤岛开采中的采煤量远高于传统技术,在开采25 d时,采煤量超过7万t,提高了孤岛开采的采煤量,减少了资源浪费。
Due to the unreasonable layout of the working face in traditional island mining technology, the amount of coal extracted during island mining was low. Therefore, research on technology of island mining under complex conditions in fully mechanized mining faces was conducted. Firstly, it was necessary to arrange the working face and optimize its length, in order to fully utilize resources and improve coal mining efficiency. Secondly, determine the rotation radius of the mining island in order to adjust the position of the working face reasonably during the mining process. Once again, by calculating the rotation parameters of the mining island, the rotation process of the working face could be further optimized and the coal mining volume could be increased. Finally, using rotation technology to achieve island mining. The experimental results showed that the coal mining capacity of this method in island mining under complex conditions of fully mechanized mining face was much higher than that of traditional technology. In 25 days of mining, the coal mining capacity exceeded 70000 tons, which improved the coal mining capacity of island mining and reduced resource waste.
