摘要：
A non-human-entry method for extracting a desired subsurface material such as ore, wherein an access hole is drilled from surface downwardly to the material, a high-pressure fluid injection tool is lowered with or after the drill string to the material and injected outwardly to disaggregate the material and form a cavity, and the material is optionally ground to a desired size by a drill bit or other means to enable suction up production tubing with a carrier fluid to the surface. The injection tool and grinding means are preferably part of an integrated bottom hole assembly at the lowermost end of a drill string, which may include surveying equipment to measure the cavity dimensions at intervals during target material disaggregation to allow fluid injection adjustment to seek to achieve a desired cavity geometry. Deck cementing is optionally employed for ground support.
摘要（中）：
用于提取期望的地下材料如矿石的非人进入方法，其中从表面向下钻探入孔到材料，高压流体注入工具在钻柱之前或之后被下降到材料并注入 向外分解材料并形成空腔，并且通过钻头或其它方式将材料任选地研磨成所需尺寸，以使得能够将具有载体流体的生产管道吸入表面。 注射工具和研磨装置优选地是在钻柱的最下端处的集成底部孔组件的一部分，其可以包括测量设备，以在目标材料解聚期间间隔地测量腔体尺寸，以允许流体注射调节以寻求实现 期望的腔几何。 甲板固井任选用于地面支撑。
