In order to meet the requirements of lightweight and explosion-proof safety of coal mine equipment, a type Ⅰ non-metallic lightweight explosion-proof enclosure with a volume of 19.5 L was prepared by glass fiber/epoxy resin composite (GF/ER). The comprehensive performance of GF/ER explosion-proof enclosure was analyzed by material performance tests, finite element simulation and multiple explosion-proof safety tests. The results show that the GF/ER explosion-proof enclosure meets the requirements of high mechanical strength, high flame retardancy (V-0 grade) and antistatic property of underground coal mine equipment. The change rates of tensile properties, bending properties and impact strength of GF/ER explosion-proof enclosure are less than 10%, indicating that it has excellent durability and environmental adaptability. In the reference pressure test, the maximum explosion pressure of the GF/ER explosion-proof enclosure is 0.496 MPa, the ultimate bearing capacity is 3.1 MPa, far exceeding the standard requirement of 1.5 MPa. Under the working load, the gap deformation of the GF/ER explosion-proof enclosure is less than 0.15 mm, and the structure is stable and reliable. Compared with the same size metal explosion-proof box, the GF/ER explosion-proof enclosure achieves more than 50% weight reduction effect, significantly reduces the burden of downhole operation, and improves the endurance of mobile equipment. The research results can provide a feasible technical path and theoretical basis for the lightweight of mining equipment.

为满足煤矿井下设备轻量化与防爆安全需求，采用玻璃纤维/环氧树脂复合材料（GF/ER）制备出一种容积为19.5 L的Ⅰ类非金属轻型隔爆外壳，并通过材料性能测试、有限元仿真及多项防爆安全试验分析GF/ER型隔爆外壳的综合性能。结果表明：GF/ER型隔爆外壳满足煤矿井下设备对高力学强度、高阻燃性（V-0级）和抗静电性的要求；GF/ER型隔爆外壳的拉伸性能、弯曲性能及冲击强度变化率均小于10%，表明其具有优异的耐久性和环境适应性；在参考压力测试中，GF/ER型隔爆外壳的最大爆炸压力达0.496 MPa，极限承压能力为3.1 MPa，远超标准要求的1.5 MPa；在工作载荷下，GF/ER型隔爆外壳隔爆面间隙变形小于0.15 mm，结构稳定可靠；与同等尺寸金属隔爆箱相比，GF/ER型隔爆外壳实现了超过50%的减重效果，显著降低井下作业负担，提升了移动设备续航能力。研究成果为矿用装备轻量化提供了可行的技术路径和理论依据。
