摘要
以莒山矿9号煤层综采工作面为例,分析了9号煤层工作面充填技术的必要性和技术可行性。通过对现有充填技术进行对比分析,确定9号煤层采用综采泵送膏体充填技术。在此基础上,对充填工程投资进行估算,并进行充填效益分析。结果表明,9号煤层采用充填开采技术,企业可以取显著的得经济效益。
The necessity and technical feasibility of flling technology for the No.9 coal seam working face in Jushan Mine are analyzed by taking the No.9 seam working face as an example.By comparing and analyzing the existing filling technology,it is determined that the No.9 coal seam adopts the filling technology of pumping paste for comprehensive mining.On this basis,the investment of flling project was estimated and the benefit analysis of flling was carried out.The results show that the enterprises can get significant economic benefits by adopting the flling mining technology in No.9 coal seam.
