Method for utilizing underground coal gangue of underground coal mine
The invention relates to the technical field of coal treatment, in particular to an underground coal mine underground coal gangue utilization method, which comprises the following steps of: 1, collecting underground coal gangue, and transporting the underground coal gangue to a to-be-hardened bottom plate roadway to be stored for later use; 2, the underground coal gangue is crushed through a crusher; 3, adding the crushed underground coal gangue, cement, a curing additive and water into a stirrer, and mixing and stirring to obtain a mixture; and 4, conveying the mixture obtained in the step 3 to a to-be-hardened bottom plate roadway, performing paving forming, and performing maintenance so as to obtain the hardened bottom plate roadway. The underground coal gangue of the underground coal mine is directly applied to hardening of the roadway bottom plate, the utilization rate of the underground coal gangue is high, and the additive is environment-friendly and easy to degrade.
本发明涉及煤炭处理技术领域,具体涉及一种井工煤矿井下煤矸石利用方法,步骤一:对井下煤矸石进行采集,运输至待硬化底板巷道储存待用;步骤二:使用破碎机将井下煤矸石进行破碎;步骤三:将经过破碎处理后的井下煤矸石、水泥、固化添加剂和水加入至搅拌机中混合搅拌,得到混合料;步骤四:将步骤三所得混合料运送至待硬化底板巷道,摊铺成型,养护后得到硬化底板巷道。本发明将井工煤矿井下煤矸石直接应用于巷道底板硬化,井下煤矸石利用率高且添加剂环保易降解。
