摘要
井下混凝土强度直接关系着煤矿矿井支撑结构的安全性。水灰比和水泥等级、粗骨料、温度、龄期等均会对煤矿井下混凝土的强度产生作用,针对诸多影响因素,针对性的提出井下混凝土强度改良措施。期望能进步一提升井下混凝土强度,创造稳定、良好的井下支撑环境,确保煤矿矿井生产的安全性。
The strength of underground concrete is directly related to the safety of coal mine supporting structures.Water-cement ratio,cement grade,coarse aggregate,temperature,age,etc.will all have an effect on the strength of underground coal mine concrete.In view of many influencing factors,targeted measures to improve the strength of underground concrete are proposed.It is expected to improve the strength of underground concrete,create a stable and good underground supporting environment,and ensure the safety of coal mine production.
