In order to solve the problem of roof instability and material waste caused by unreasonable value of roof support parameters, the optimization of support parameters was studied based on the research background of the north stope of Zhongguan Iron Mine. Firstly, based on the suspension theory and the loose circle theory, combined with the numerical simulation results without support, the plastic zone was used as the basis for the determination of the loose circle, and the thickness of the loose zone was obtained, and then the length of the bolt was 2.4−4.4 m. Secondly, according to the quality of rock mass, the designed row spacing between bolts was 0.8 m×0.8 m and 1.2 m×1.2 m respectively, the length of bolts was 2.4 m and 4.4 m respectively, and the anchoring force was 17.5 MPa and 20 MPa respectively. The FLAC3D software was used to establish the mining model, and the vertical stress, vertical displacement and plastic zone distribution of the roof of each scheme were compared and analyzed. Finally, based on the simulation results, the index satisfaction method was used to select the roof settlement, the height of the stress release zone, the area of the plastic zone and the total length of the bolt, and the optimization model of the bolt parameters considering the safety and economic benefits was established. The highest comprehensive satisfaction is 0.899, and the optimal scheme is determined to be a row spacing between bolts of 0.8 m×0.8 m, bolt length of 4.4 m and anchoring force of 20 MPa. The simulation results provide theoretical support for the determination of the bolt parameters of the ore body.

为解决顶板支护参数取值不合理导致顶板失稳、材料浪费的难题,以中关铁矿北区采场为研究背景,进行支护参数优化研究。首先,基于悬吊理论和松动圈理论,并结合未支护时数值模拟结果,将塑性区作为松动圈判定依据,得出松动区厚度,进而得出锚杆长度为2.4~4.4 m;其次,根据岩体质量,设计锚杆间排距分别为0.8 m×0.8 m和1.2 m×1.2 m,锚杆长度分别为2.4 m和4.4 m,锚固力分别为17.5 MPa和20 MPa,采用FLAC3D软件建立回采模型,对比分析各方案顶板竖向应力、竖向位移、塑性区分布规律;最后,以模拟结果为基础,采用指标满意度法,选取顶板沉降量、应力释放区高度、塑性区面积以及锚杆总长度等指标,建立了综合考虑安全与经济效益的锚杆参数优选模型,计算得出综合满意度最高为0.899,确定锚杆间排距0.8 m×0.8 m、锚杆长度4.4 m、锚固力20 MPa为最优方案。模拟结果为该矿体锚杆参数的确定提供了理论支撑。
