10+ Arrowpoint Technologies Interview Questions and Answers

Board and pillar method is a mining technique where a network of rooms is created with pillars of ore left in place to support the roof.

• Involves creating a network of rooms separated by pillars of ore

• Pillars are left in place to support the roof

• Commonly used in coal mining

• Allows for efficient extraction of ore while maintaining structural integrity of the mine

Geothermal gradient affects productivity by influencing the temperature of the subsurface, which can impact the efficiency of geothermal energy extraction.

• Geothermal gradient refers to the rate at which temperature increases with depth in the Earth's crust.

• A higher geothermal gradient can result in higher temperatures at shallower depths, making geothermal energy extraction more efficient.

• Conversely, a lower geothermal gradient may require drilling deeper to reach optimal tem...read more

I follow a systematic approach, prioritize tasks, communicate effectively, and adapt to changing conditions.

• Prioritize tasks based on importance and deadlines

• Communicate effectively with team members and supervisors

• Adapt to changing conditions and adjust plans accordingly

Gasiness refers to the presence of gas in a substance or environment.

• Gasiness can be measured by the amount of gas present in a given volume of a substance.

• In mining, gasiness is important to monitor in underground mines to prevent explosions.

• Common gases found in mines include methane, carbon monoxide, and hydrogen sulfide.

Productivity is the measure of efficiency in completing tasks and achieving goals.

• Productivity is the ratio of output to input in a given period of time.

• It involves maximizing output while minimizing input.

• Examples include completing tasks in a timely manner, meeting deadlines, and achieving targets efficiently.

Data is information that is collected, stored, and analyzed. Excel is a spreadsheet software used for data management and analysis.

• Data refers to any information that can be processed by a computer.

• Excel is a popular spreadsheet software used for organizing, analyzing, and visualizing data.

• Excel allows users to perform calculations, create charts and graphs, and manipulate data in various ways.

• Data in Excel can be sorted, filtered, and searched to extract meaningful insights....read more

MS PowerPoint is a presentation software developed by Microsoft.

• It allows users to create and edit slides with text, images, and multimedia.

• Users can also add animations, transitions, and other effects to their presentations.

• PowerPoint is commonly used for business presentations, educational lectures, and personal slideshows.

• It is part of the Microsoft Office suite of applications.

• PowerPoint files have a .ppt or .pptx file extension.

I can type a letter within 5 minutes.

• Start with a proper salutation and introduction

• State the purpose of the letter clearly

• Provide necessary details and information

• End with a polite closing and signature

• Proofread for errors before sending

MMV (Multi-Methodical Verification) is a process used in underground coal mines to ensure safety and efficiency.

• MMV involves using multiple methods to verify the safety and efficiency of mining operations.

• These methods may include visual inspections, gas monitoring, and equipment testing.

• MMV is important for preventing accidents and ensuring that the mine is operating at maximum efficiency.

• For example, if gas levels are found to be too high during an MMV inspection, work may ...read more

MMV is a mining method used in underground coal mines to extract coal seams.

• MMV stands for 'Midi-Mining-Voûte' which means 'medium mining arch' in French.

• It involves the use of a continuous miner machine to extract coal from the seam while leaving behind pillars of coal to support the roof.

• The pillars are then gradually removed and the roof is allowed to collapse behind the mining machine.

• This method is used in low to medium height coal seams and is considered safer than othe...read more
