摘要
两市镇缓倾斜石膏矿床采空区稳定性的影响因素，主要有矿体顶板硬壳——青膏层的厚度薄，易吸水软化，抗压抗剪强度低；区内局部节理发育、层理密集；地下水活动以及开采不规范等。针对采空区的顶板厚度、稳固性、矿柱强度等稳定性参数，预测了采空区危险地段，建议对采空区采取监测、封闭、排水、充填、联合支护等既安全又经济可行的防治措施。
The stability of the goafs of Liangshi gypsum deposit is mainly influenced by the small thickness,water-absorption and low strengths of compression and shear of the upper walls of the orebodies;and by the clearages and bedding ;as well as the undergraound water activity and irregular mining.By evaluating the stability parameters such as the upper wall thickness,solidness and the strength of the mine props,etc,dangerous area of the goafs are predicted. Practical and economic protection measures are proposed for the goafs.
