摘要
为缓解采掘接替紧张局面,需对87采区上方含水层下薄基岩浅埋煤层870、871、872工作面进行安全回采。朱仙庄煤矿通过合理配备综采设备、在回采过程中对矿压进行密切监测、采取适当的顶板控制及防治水措施,成功实现了870、871、872工作面放顶煤开采,创造了可观的经济效益。
To insure the normal mining-excavating alternating, 870,871,872 working face under aquifers in shallow-buried coal seam with thin bedrock should be mined. To do this,these measures were carried out in Zhuxianzhuang Coal Mine,such as allocating the device reasonably, making observation strata behaviors frequently during the mining procedure, adopting appropriate roof and water control measures. By these measures, top coal caving was successfully realized, and significant economic benefits had been created.
