Abstract To solve the problem of surface subsidence caused by mining，the main methodis to reasonably process coal mining space．「Mining caving zone high—pressure groutingpulverized coaI ash hydromass controlling roof and overlying strata movement'』technologyis one of processing methods．After grouting pulverized coaI ash hydromass in miningcaving zone，formed one kind of special materia1 which is used to support roof and efectivelycontroI the subsidence of overlying strata．For the accurate calculation of roof miningsubsidence at grouting state，based on the characteristics of such materials，establishedits constitutive equation based on certain assumptions。gave deformation calculation method when the compound ro ck supports overlying strata．1ay foundation for the actuaI
calculation of subsidence of overlying strata after grouting and the promotion of mining ca ving zone grouting technology．

Surface subsidence caused by mining not only damages the ecological environment in mining area，but also damage building and structures on ground surface and causes seriOUS security risks．The main method to solve these problems is to reasonably proc． ess coal mining space．Different from the traditional method of goaf hydraulic stowing，broken rock grout-
ing and metal mining field paste body grouting，some scholars propose 「mi ning caving zone high—pressure grouting pulverized coal ash hydromass controlling roof and overlfing strata movement』'technologyl to control the movement of roof and overlying strata then proceed to rece surface subsidence．The basic men．tality of this technology is to design a subcritical exaction working surface in mining zone．Extract a grouting gallery over the caving zone which is parallel to road serving for working face，and arrange centralized grouting tube in grouting gallery over the caving zone．Drill hole in rock every certain distances deep into caving zone．The drill hole in rock is ve~ical to grouting road．It can grout into caving zone with the working surface moving forward．As a result，com．pound rock is formed to support the roof then control the movement of overlying strata.
Therefore，the roof control quantity is compres．sion quantity of compound

rock after caving zone grouting，so it is essential to study on the deform ation under overlying strata pressure ring the process of overlying strata.

2. 挖礦軟體哪個最好用啊求推薦

哈魚礦工啊，Windows可一鍵挖礦，而且還沒有抽水。同時，他們也有APP，可以隨時監控你的機器。

Linux系統也可以挖礦，兩步設置，就可以挖礦。

Linux系統兩步搞定挖礦

• 打開網站，輸入手機號，選擇你要使用多少CPU來挖礦，默認為使用50%的CPU進行挖礦，點擊生成你的專屬命令並復制



就是這么操作簡單。
