新疆阿拉安道南矿井首采区B_3煤层采煤方法选择

Selection of mining method of the first mining area B_3 seam in Xinjiang An daonan mine

针对阿拉安道南矿井首采区B3煤赋存情况,通过对分层综采、大采高一次采全厚综采和综采放顶煤适应性分析,对其三个采煤方法从不同方面进行了有针对性的比较,研究认为综采放顶煤更有利于矿井安全高效开采,提高煤炭资源回收率,对本矿井乃至新疆地区厚煤层开采提供了宝贵、可靠的经验,对大幅提高厚煤层放顶煤工作面单产具有重大的意义。

Aiming at the first mining area B3 coal occurrence of Allah, by analyzing the adaptability of fully mechanized slicing mining, fully mechanized mining once mining full thickness and fully mechanized top coal caving, the study suggest that the fully mechanized top coal caving is more conducive to the mine safety and high efficiency mining, is more favorable to improve the recovery rate of coal resources, which provides valuable and reliable experience for the mine, and Xinjiang area of thick coal seam mining, is of great significance to greatly improve the yield of thick seam caving face
