1.He expects to inherit a large estate left by his grandfather. To his disgust, he learns that the bulk of the estate has been left to his distant cousin.
2.The "broken post"and broken range section in the concrete frame post will reduce the vertical supporting loads and the ability of existing erathquakes,so the quality and the technique of construction should be strictly controlled.
3.The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed, in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage, put forward the isolated section-grouting technology for overburden bed separation space, integrated the virtue of growing for bed separation space and partial extraction, the bed separation grouting bodies, key stratum and isolated section pillars were made to constitute the load-carrying body all together, and to reach the purpose of reducing subsidence effectively, increase the coal seam extraction ratio, and accelerate the development of isolated section-growing technology for overburden bed separation space.
