摘要
应用室内相似材料模拟和地表钻孔实测方法,对沙吉海煤矿侏罗系中统厚煤层综放开采的覆岩破坏特征进行研究,实测得出了该矿B10煤层开采的覆岩破坏高度,明确了采动裂缝发育的基本特征。研究表明,B10煤层开采的覆岩破坏最大高度可以按照裂采比13.59、垮采比3.80进行预计。研究结论可为沙吉海煤矿及新疆地区类似条件矿井受水害威胁煤炭资源的安全回收提供可靠的数据支撑。
Overburden strata broken character of fully mechanized top coal caving with thickness coal seam of Middle Jurassic in Shajihaicoal mine were studied by similar material simulation indoor and surface drilling. The overburden strata broken height of B10 coalseam mining was obtained by filed research, the basic characters of mining fracture zone development was determined. The researchshowed that the maximal overburden strata broken height of B10 coal seam could be predicted according fracture-mining ratio 13. 59 andcollapse-mining ratio 3. 80. The conclusions could referenced for coal resources recovery that influenced by water of Shajihai coal mineor other similar coal mine in Xinjiang.
