针对斯列萨列夫公式在矿井水害防治中的广泛应用并被写入《煤矿防治水规定》等相关文献和书籍中,运用材料力学原理论证了防隔水煤岩柱留设宽度、探放水钻孔超前距及止水套管长度公式是基于简支梁模型的理论公式,安全水头及安全隔水层厚度公式是基于超静定梁模型的理论公式。因简支梁模型理论公式实际运用时存在力学误差,为防止计算L值过小导致突水事故发生,强调斯列萨列夫防隔水煤岩柱留设宽度、探放水钻孔超前距及止水套管长度公式增加安全系数K及在此基础上仍需遵守《煤矿防治水规定》的必要。因回采工作面底板矿压显现规律明显及承受的压力非均布载荷,强调斯列萨列夫安全水头及安全隔水层厚度公式仅适用于掘进巷道突水危险性评价。
Aiming at the extensive application of Slysarev formula in the prevention and control of mine water damage, it was written into relevant literature and books such as “Coal Mine Prevention and Control Water Regulation”, and the principle of material mechanics was used to demonstrate that the width of water- Drilling distance and water stop casing length formula is based on the simple beam model of the theoretical formula, safety head and safety layer thickness formula is based on statically indeterminate beams theoretical formula. Due to the mechanical error in the practical application of the simply supported beam model formula, in order to prevent the occurrence of water inrush accident caused by the calculation of L value too small, the emphasis is placed on the reserved width of Sliese Lev anti-sequestration coal and water pillar, Water cannula length formula to increase the safety factor K and on this basis still need to comply with “Coal Mine Water Regulations” necessary. Because of the obvious law of underground pressure and the non-uniform load under pressure, it is emphasized that Slysarev safety head and safety aqueduct thickness formula are only suitable for the evaluation of water inrush hazard of roadway.
