顾北煤矿13521采区注浆效果治理多因素综合模拟评价

Comprehensive Simulation Evaluation of the Effect of Slurry Injection in 13521 Mining Area of Gubei Coal Mine

摘要: 近年来，伴随着东部矿区浅部资源开采殆尽，为满足资源需要，因此煤矿开采也由浅部开采发展到深部开采。深部煤层开采所带来的“三高一扰”即高地应力、高地温、高水压及剧烈开采扰动条件下导致的深部煤层开采难题，其中对于高水压所带来的突水问题尤其严重。顾北13521工作面由于开采深度增加，底部太原组灰岩岩溶裂隙承压含水层对工作面开采影响较大，所以为降低开采风险急需进行地面区域治理。现阶段对于区域治理比较高效的方法是注浆加固。本文以东部顾北煤矿13521工作面注浆区域治理工程为例，结合注浆实际评价效果与AHP模拟评价进行比较，与实际比较有一定的可靠性。

Abstract: In recent years, along with the exploitation of shallow resources in the eastern mining areas, in or-der to meet the needs of resources, coal mining has also developed from shallow mining to deep mining, and the “three highs and one disturbance” brought about by deep coal seam mining is the problem of deep coal seam mining caused by high stress, high temperature, high water pressure and severe mining disturbance. Among them, the problem of sudden water caused by high water pressure is particularly serious. Gubei 13521 work surface due to the increase in mining depth, the bottom Taiyuan group ash karst crack pressure aquifer has a greater impact on the working surface mining, so in order to reduce mining risk, there is urgent need to carry out ground area manage-ment. At this stage, it is more efficient method for regional governance: injection reinforcement. In this paper, taking the regional management project of 13521 working surface slurry in the eastern Gubei coal mine as an example, this paper compares the actual evaluation effect of slurry with the simulation evaluation of AHP, and has some reliability compared with the actual comparison.
