mining subsidence area的意思|示意

This III chapter is introduced in detail, analyzes the five mining subsidence area of land use status and the problems faced.

本章详细介绍了五大矿区概况，分析了沉陷区土地利用现状及面临的主要问题。

The results can provide theoretical basis and scientific references for Kailuan mining area and similar mining area to predicting and controlling surface subsidence and mining under the "three body".

本文的研究成果对开滦矿区深部开采及类似矿区的地表沉陷预测及控制、“三下”采煤具有一定的理论价值和指导意义。

The model can exactly forecast the mining subsidence that is caused by complex geological conditions and the irregular working out area.

该模型能够对复杂地质条件和不规则采空区引起的地表沉陷进行较为准确地预测。

The stability of tunnel in mining-coal induced subsidence area is a complicated problem because of the influence of tunnel excavation and strata displacement induced by mining.

采煤塌陷区隧洞围岩稳定性，既受隧洞自身开挖的影响，又受洞下采煤引起地层移动的影响，是一个极其复杂的问题。

The measured data of the mining area are used to verify the model with the expected results of the maximum relative error 9%, which can meet the requirements of mining subsidence.

采用某矿区实测资料对模型进行验证，预计结果最大相对误差9%，可以满足矿山开采沉陷预测的要求。

The practlce has shown that the overlying separate seam grouting is a positive, effective and economic new-countermeasures on the control and treatment of mining-area subsidence.

实例证明，覆盖离层注浆是治理矿区塌陷环境的积极的、有效的、经济的新对策。
