摘要:
煤层瓦斯压力测定是煤矿安全生产基础参数测定的重要内容之一，测压成功的关键是封孔技术。当围岩裂隙较发育时需要采用压力注浆封孔，注浆压力就成为封孔的技术关键。为了确定一定围岩岩性条件下的合理封孔注浆压力，采用数值模拟的方法对测压钻孔塑性区大小进行了仿真模拟，并根据浆液渗流规律和钻孔围岩性质之间的关系建立了浆液流动数学模型，得出了合理的注浆压力为4MPa，结合新型“两堵一注”囊袋式封孔装置与CPD8M型煤层瓦斯压力自动测定仪进行了现场应用，结果表明4MPa的注浆压力满足平煤十三矿试验现场围岩条件下的封孔要求，对同类条件下瓦斯压力测定具有一定的指导意义。
Abstract:
Coal seam gas pressure measurement is an important part of the basic parameter determination of safety production in coal mine, the key to successful manometry is sealing technology. When the surrounding rock fracture is developed by using pressure grouting hole needs, grouting pressure has become the key technology of hole sealing. In order to determine a reasonable hole sealing grouting pressure of surrounding rock lithology conditions, using numerical simulation method to pressure hole the size of the plastic zone is simulated, and the establishment of slurry flow mathematical model according to the relationship between the flow of slurry and drilling properties of surrounding rock, grouting pressure obtained reasonable 4MPa, combined with the new "two block a injection" bag type sealing device and CDP8M type coal gas pressure automatic measuring instrument for field application, the results show that the grouting pressure 4MPa meet thirteen min of Ping dingshan mining site test of surrounding rock conditions of sealing requirements, it has certain guiding significance for similar conditions of gas pressure determination.
