为了研究水泥掺量、综合水灰比、地层特征等因素对煤矿等厚度水泥土截水帷幕性能的影响，开展了等厚度水泥土帷幕原理分析、帷幕性能影响因素分析等厚度水泥土试验和性能测试，确定了关键影响因素，得出了复合地层等厚度水泥土参数，并进行了现场示范应用。研究结果表明：等厚度水泥土截水帷幕性能的影响因素主要为岩（土）体性质、地下水特征、水泥胶凝材料、混合过程和养护条件；岩（土）体性质和水泥掺量是影响墙体质量的直接因素，水灰比和养护周期是保证墙体质量的关键因素；当地层自身强度较高、颗粒级配较好，等厚度水泥土强度高，渗透系数小；根据影响因素确定示范工程的水泥掺量为25%、综合水灰比为1.2∶1、地层为复合地层材料。骆驼山煤矿缓坡斜井井筒复合地层渗漏段治理结果显示，采用3步施工法工艺构筑的斜井外侧截水帷幕墙体质量好，现场试样28 d抗压强度为5.3~31.8 MPa，渗透系数为0.005×10⁻⁷~0.2403×10⁻⁷ cm/s，井筒涌水量由16.8 m³/h降低至1.6 m³/h，较治理前减少了90.5%。

In order to study the influence of cement content, comprehensive water-cement ratio, formation characteristics and other factors on the performance of equal thickness soil-cement cut-off curtain in coal mine, the principle analysis of equal thickness soil-cement curtain, the influencing factors of curtain performance analysis, the test and performance test of equal thickness soil-cement curtain were carried out, the key influencing factors were determined, the parameters of soil-cement of equal thickness in composite strata were obtained, and the field demonstration application was carried out. The results show that: the main factors affecting the performance of equal thickness soil-cement curtain were rock (soil) body properties, groundwater characteristics, cement cementitious materials, mixing process and curing conditions. Rock (soil) body properties and cement content were the direct factors affecting wall quality; water-cement ratio and curing period were the key factors to ensure wall quality. The ground layer had higher strength and better grain gradation, so the strength of soil-cement of equal thickness was higher and the permeability coefficient was smaller. According to the influencing factors, the cement content of the demonstration project was determined to be 25%, the comprehensive water-cement ratio was 1.2:1, and the formation was composite formation material. The treatment results of the complex formation leakage section of the gentle slope inclined shaft in Luotuoshan Coal Mine showed that the three-step construction process was used to construct the outer water cutting curtain wall of the inclined shaft with good quality. The 28 d compressive strength of the field samples was 5.3—31.8 MPa, and the permeability coefficient was 0.005×10⁻⁷—0.2403×10⁻⁷ cm/s. Wellbore water inflow decreased from 16.8 m³/h to about 1.6 m³/h, which was reduced by about 90.5% compared with before treatment.
