深部倾斜煤层动压巷道围岩控制技术研究

为了解决庞庞塔矿深部倾斜煤层工作面回采巷道受侧向工作面采空产生的高集中应力和动压影响造成的支护困难问题，采用了支护材料、方法和支护参数优化设计，以达到减小巷道整体表面变形，保障回采工作面安全、高效开采的目的。根据庞庞塔矿5-107工作面回采巷道实际条件，研发了尺寸为150×150×10mm的高强度方形带拱锚杆托板和尺寸为300×300×16mm的高强度方形带拱锚索托板，提出了及时高预紧力、强力锚杆锚索、强护表构件和强帮支护的耦合支护技术，对5-1071巷和5-1072巷进行了支护参数优化设计，巷道矿压监测数据的分析结果表明，优化设计后的巷道变形处于可控范围。

Study on surrounding rock control technology of dynamic pressure roadway in deep inclined coal seam

In order to solve the problem of support difficulty caused by the high concentrated stress and dynamic pressure produced by the goaf of lateral working face in pangpangta coal mine, the optimization design of support materials, methods and support parameters was carried out, so as to reduce the overall surface deformation of roadway and ensure the safety and efficient mining of mining face. According to the actual conditions of mining roadway in 5-107 working face, the high-strength square arch bolt supporting plate with 150 × 150 × 10 mm and the high-strength square arch anchor cable supporting plate with the size of 300 × 300 × 16 mm are developed. The coupling support technology of timely high preload, strong bolt anchor cable, strong protection surface component and strong side support is proposed. The supporting parameters of 5-1071 and 5-1072 roadway are optimized, The analysis results of mine pressure monitoring data show that the roadway deformation after optimization design is within the controllable range.
