建筑地坪在煤矿底鼓治理的应用实践

Application practice of building floor in coal mine floor heave control

从煤矿底鼓治理问题出发,分析并研究了建筑地坪与煤矿地坪的差异因素和地坪承载因素,通过理论计算和数值模拟,验证了建筑地坪在煤矿底鼓治理中的作用效果。结果表明,煤矿地坪的施工难度更大;基础承载力、混凝土标号、地坪厚度和设计形式是影响地坪承载性能的关键因素,理论计算初步设计的煤矿地坪的极限承载力为32.109 t;建筑地坪对于煤矿底鼓治理具有一定效果,其中混凝土标号为35,地坪厚度为20 mm时,底鼓治理效果最佳,建筑地坪能够为地下空间工程的灾害治理,提高建筑空间的安全稳定提供新策略。

This paper takes the coal mine bottom drum control problem as a starting point,analyzes and studies the difference factors and bearing factors of building ground and coal mine ground,verifies the effect of building ground in coal mine bottom drum control through theoretical calculation and numerical simulation.The results show that the construction difficulty of coal mine ground is greater;foundation bearing capacity,concrete grade,ground thickness and design form are the key factors affecting the bearing performance of ground,and the theoretical calculation of the initial design of coal mine ground the ultimate bearing capacity is 32.109 t;the building ground has certain effect on the coal mine bottom drum treatment,among which the concrete grade is 35,the ground thickness is 20 mm,the bottom drum treatment effect is the best,the building ground can provide new strategies for the disaster control of underground space engineering and improve the safety and stability of building space.
